Brewing PBR "crap" is hard....perhaps the most difficult beer to home brew (debate amongst yourselves). So, if that is what you are trying to avoid, good, it would be expensive to try to do that (see thread from guy with three converted chest freezers....I bet he could brew something close to pbr, if he wanted to).
A $1000 could buy you over 1/3rd of the http://www.brew-magic.com/rims_brwy_pro.html
cheapest sabco brewing system. And that doesn't include fermentation or bottling equipment. At a minimum a basic set up to do extract brewing could cost probably $100-$200. You can spend as much as you want on whatever gadgets you can think of. Some are useful, some are not.
In this case, spending $1000 right out of the gate doesn't make a lot of sense. If you buy good expensive equipment and don't know how to use it, it is useless. If you buy an expensive system for all grain and use it just for extract, most of the $$ are wasted. If you buy expensive temperature control systems and only do ales your money is not very well utilized. Each of our brewing rigs were developed for our personal brewing styles and tastes as well as the type of brewing and types of beers we like to brew. They were considered investments after we figured out how to brew. some will spend $5000 on the turn key automated system, some will spend a couple of hundred on raw materials and MacEyver their own systems (as complex as the $5000 system). Mine is in the middle.
The best way to start is read Palmer's and/or Papazian's excellent books on brewing. They give you basic ideas of what is necessary for each level of brewing (and what they are, for that matter). After that, a local home brew store...being near SF you have a lot of excellent stores to choose from, will be able to help you spend $$ on good equipment (craigslist works, but you need to know what you are buying) for beginning. If you want to spend $1000 at that point, go for it....but I would go with a good kit. I started on the Williams brewing kit almost 20 years ago (williams is one of the local shops you have in the SF bay area). I was happy with that kit for more than 5 years, and made successive purchases and builds to my current all grain manual control, fire brewed rig (valued only at $1,000 or thereabouts in parts, not including my labor of assembly, of course).....of course, I also triple hop (often) and cold filter too. But my crap doesn't taste like PBR (which I like btw)....PBR is sold so cheaply that it is not worth brewing myself (for the effort).
