Alot of it is going to depend on what you want to do, you kinda sound like me do it yourselfer on alot of small house projects and want the tools to make life a little easier.
I bought a package deal at sears that came with the compressor below and a set of 3 nail guns. and i bought just one of there base model mitre saws, a rip saw is wonderful to have if you actually plan on cutting longer material.
I also have one of there table saws that i picked up on sell.
Never once have had a problem, but i do have a 100 gallon in the workshop for running air tools etc, but the pancake one below works beautifully with nail guns and other small projects.
