Economical grinders?

[Sauer Grapes]

I am a complete coffee noob. I think I am going to ask for a grinder for valentine's day, or at least something coffee related.

I don't have anything right now other than coffee cups. I will probably brew using a press, as I think it'll be most economical in the long run, and I don't mind it not being "automated." I saw some threads on here mentioning a press brand (bodum I think). I know they have those at bed bath and beyond which is in walking distance.

Anyway, besides the press, I know I'll need a grinder. Is there anything else I'll need (besides some beens)?

Also, what is a decent, but inexpensive grinder that will grind beans for use in a press?

Also, also... taking the brew to work in a thermos or similar won't affect the taste much will it?

Thanks!
