decent beginner amplifier rec's

Hey all, new audiophile in training..heh.

Going to be purchasing an amplifier for two bookshelf/monitor speakers I am running computer sound through (for production work) and was wondering if there were any of you who would recommend a certain brand or model.

I am not looking to spend a fortune, just want an idea of what some entry level amps would cost/be like.

Thanks, Caleb
