I think you've received a lot of good advice, Gresch.

If your goal is to minimize your cost for the clubs and just go out and have fun, eBay or craigslist is a good option if you know what flex you need and like a particular club. X-16, X-18 or X-20 Callaways would be good choices, IMO, but I wouldn't recommend the "pro" models of those which are smaller and less forgiving.

If your goal is to improve, I suggest working with a golf pro or a store that will fit you properly and let you try out the clubs before you purchase them.

Personally, I don't like the look of hybrid clubs. I usually carry a 7-wood instead of a 3-iron. My current irons are Nike forged CCis which are muscle back design (the regular CCis are cavity back). A little above my ability but I'm still trying to improve and like the feedback they give on each shot.
