THIS^^^^ Expensive equipment is something you want, not need. If you truly want to brew it can be done on a shoestring.
I agree, but at this point in my life, I know the difference between quality and make-do gear. For example, a keggle costs next to noting if one can look past the fact that the keg is owned by the brewery embossed on it. I personally would never use a keggle again because keggles are horribly inefficient to heat. I only purchase or build kettles with welded fittings. That has been my personal preference since I built my first and only keggle. One area where I have become more flexible is fermentation vessel material. I only fermented in glass after I acquired my first 6.5 gallon acid bottle. At that point in time, I would have never considered going back to buckets and their residual odors, but I was a very strong, surefooted guy when I started to brew. Glass is not even on my radar these days and it was not on my radar during my previous pass through the hobby. That being said, I cannot think of another piece of gear that has increased in price as much without a corresponding increase in quality as the lowly 6.5-gallon food-grade bucket. I paid $5 for my first 6.5-gallon bucket. Some places are now charging as much as $20 for 6.5-gallon food-grade buckets.
The reality is that after one has been brewing and acquiring better gear for a number of years, it is very difficult to go back to the beginning. Plus, step-wise improvement may reduce "at time of acquisition" cost, but it raises overall cost, as the cost of previously acquired and discarded gear has to be included in total cost of ownership. While I recommend that beginning brewers start with the minimum kit they need to brew until they are certain that brewing is not a passing fad, anyone who was in the hobby for a number of years and had to take a break that was long enough to sell off gear should think long and hard about taking that path. It is better to "buy once, cry once" if one knows what one wants. Sure, it will take one longer to start back up because few people can lay out that much money at one time without taking it out of savings or going into debt. I have been acquiring gear using my monthly disposable income and I am purchasing it all new. I always shoot for the best price I can get for off-the-self gear and parts to build gear. For example, I purchased a new Taprite T742 regulator for $49.00 shipped to my home. Sure one can purchase a new T742 for $49.00 from Beverage Elements, but they charge shipping. On the other hand, I purchased a two-pack of 5-gallon AEB soda kegs for $200.00 shipped with tax from Beverage Elements. My LHBS sells the same keg for $125 each. That is a $50 savings and small savings add up while building out a new brew house, home brewing lab, and beer dispensing setup. I could purchase used kegs for half of that cost, but then I would have to rebuild them. I have had my fill of removing stickers, cleaning, and polishing, not to mention replacing o-rings, poppets, pressure relief valves, and lids. Those half-price used kegs are no longer a bargain after one has to invest $20 on complete set of o-rings and two new poppets plus a lot of one's time to bring them back into working condition. Let's not forget about the used kegs we have received that will never be gas tight. Used kegs were a bargain when they were $10 to $15 each and new kegs were over $100, but it does not make sense to blindly go used these days, not remotely so.
One area where I have killed it has been lab glassware. I always purchase new surplus if it is available. I purchased 72 new-in-box re-usuable Kimble culture tubes with caps for under $40 shipped. That is 1/4th the cost if purchased from a labware supplier and much less than what some homebrewing stores charge for non-resusable culture tubes (just because a screw cap culture tube is glass does not mean that it is re-usable). I purchased a box of six new Corning 3980 500ml Erlenmeyer flasks for under $30 shipped to my door. That is less than $5 per flask shipped to my door. MoreBeer charges almost double that price for an off-brand 500ml flask.
