While there is some satisfaction to doing it yourself and knowing what is perfect and what is not, time is also a factor. Figure you will be 2 to 5X slower than a professional.
I remodeled our kitchen this spring. Complete gut job, did all the wiring, plumbing, flooring, drywall and wanted to do the cabinet install, mainly to save money. It took the professional three complete 10 hour days to do the install. I figure it would have taken me a week to 10 days to pull off and I just didn't have that sort of time. It's all the little things that will eat your lunch like drilling for the pulls. In our area it is $1 per hole, which sounds expensive, but when you look at laying it out or purchasing a jig to center the hole and then adjustig the jig it was worth every penny. Just having the right bits and tools is problematic.
If you do decide to go after it yourself some of my favorite newer tools are:
Micro Pin Nailerhttp://www.amazon.com/Hitachi-NP35A-Gauge-Micro-Nailer/dp/B003SHDM84
You can use this to attach all kinds of molding. I even put down hickory quarter round using it (hickory is hard stuff).
My gosh there are so many uses for this, drywall, small sanding, cutting nails, you name it...LOUD!!!
I got this set for $180 and wish I had gotten the driver years ago. Great for any kind of screw or bolt.
PS: In doing the kitchen I believe I pulled out every tool in my arsenal (and they still are scattered about in my garage).
