What's your definition of a "bunch of money"? It would be easier for people to make recommendations if they knew what you budget was. To get an idea of what the various guns are going for, check out Bud's Gun Shop, http://www.budsgunshop.com/catalog/index.php/cPath/21
I'd suggest a 9mm as you get, IMO, the most bang for the buck as it's a good SD round and doesn't break the bank at the range. Without knowing what price range you're in, it's hard to make a suggestion as to brand.
Don't over-look any certified used guns either! I just bought my Sig- sauer p229 .40 cal for $550 in new condition (gun new is around $950). Awesome quality and accuracy. Not to mention it looks good two-toned
I spend about $40 for 100 full metal jacket rounds for a day at the range ($15/hr to shoot) so I can have a decent range day for around $60
You can I'm sure find some cheaper range ammo, but for some reason everybody is buying all the ammo in my area so 9mm and .40 are readily available in only a few stores. Wal-marts are always out..
(P.s. The sigs barrel can be changed to make the gun shoot between .40 and .45 (while using the same magizine), and I think with a new magizine and barrel you can convert it to a 9mm as well.)
