air tools

It is a momentous occasion I am getting my first compressor and set of air tools. Yeah I couldn't hold back the tears. Anyway I need to know what would be the optimal setup for a home mechanic as far as compressors go? I need something that won't take more than one person to move as I do work away from home as well. But I was wondering what I should get? I won't be running more than an impact, ratchet, and maybe a hammer. I will only be running one at a time. Any ideas? Sorry if this is the wrong are to post but it seemed like the most relevant. Thanks in advance for any advice.

A 30 gallon with about a 5hp single stage motor would work fine and still be portable. If your planning on moving it pretty frequently I would get 120v. Just make sure it will push enough air for what your wanting to do.
