Decent Affordable Air Compressor, For a DIY'r Options

[beemie96]

Okay, I am planning to try to do as much work on this car as possible by myself (and beer-bribable friends (IMG:style_emoticons/default/beer.gif) ). With that in mind, I am thinking I should get an air compressor that can help me with grinding rust, removing stuck lug-bolts, and all the other great things air compressors do (like filling up tires for one).

I really don't need anything too fancy, but I want something that can run the guns effectively.

I've seen some compressors for around $200.

Example:

This one had good reviews: (oil - less)
Porter-Cable CPF23400S 3 HP, 4-Gallon Side Stack Compressor $192

And this one: (oil)
Hitachi EC12 2-Horsepower Air Compressor - $239

Any pros / cons on the oil thing?

What else am I going to need? I figure I'll need an air wrench and I want whatever kind of tool that Gint was using (pic attached) is that a grinder with a wire-cup brush? Looks like an electric actually... can I just run out and get one of those?

If you plan on doing any paint work, I think the oilless compressor is the way to go. So they say on the autobody forums. However, I must say, if all you plan on doing is rust work, you don't need a compressor. I bought one thinking I would have to use an air chisel to remove stuff, but all you really need is a spotweld cutter that ataches to your drill. Besides, impacts are for brutes, torque wrenches are for professionals. But yes, at some point you should get at least a small air compressor. If you forsee any paint work, then go with a 30 gal. compressor, if not 10-15 gal will be fine.
