need some advice on a monitor

hello, I just ordered the new dual 1.8 G5 and I was wondering which display I should get....theoretically and eventually I will be getting the 23inch cinema display but since I'm still on college ($$$) is an issue, instead for now I will have to settle for maybe a sony vaio 15inch or maybe some other moderately priced monitor.....my question is which other monitors besides apple are compatible with the new 1.8 g5s and also, if anyone knows, which one is the best bang for my buck (so to speak)...thanks
