I got the pretty cheap Fostex ones. Around $200 for the pair at Long & McQuades. I've listened to 100's of C.D.'s on them. Very clear. I can hear the reverb on most albums like I've never heard it before. The low-end is alot better than I thought it would be. I still don't see a need for buying a sub yet...YET!
Definitely not the best monitors but I enjoy them alot.
I've mixed many projects on my KRK Rokit 5's. I can tell you that they are terribly INACURRATE by themselves. Once again, my opinion is different than many of the posters here. They make GREAT speakers, but that's not what you want in a monitor. So I don't recommend the KRKs...unless you'd like a nice set of speakers for your digital piano...they work great in that application. I would call some of the major recording studios in your area, and see what small monitors they're using. ACCURATE monitors are what you are after, accurate in the sense of eq, separation, clarity and dynamics. Believe or not, I have a great set of Beyer Dynamic headphones that are far more trusty than my KRK's! And they were $200.00. Peace, Jon.
$300??? ok, I strongly recommend something from Paradigm. They used to make a line of speakers called the "Monitor" series and the smallest model in that line is an accurate, neutral little speaker, with more than adequate power handling for near-field listening. I am speculating that it would serve your needs as well as a product designed for proper studio monitoring.
My advice at this price point would be to check out some consumer manufacturers.

On a budget, I've had very good experience with Tannoy monitors. Not sure you'd find anything in the $300CDN range, though. I like Paridigm nearfields too, that's not a bad recommendation.
Overall, I second staying away from something that "sounds good" - instead, I'd recommend looking for something that has good fidelity. In other words, if you can, bring a mix that you recorded and compare the tone of the monitors to the tone of the source when the stuff was recorded. Lots of recording gear has its own sound. I tend to like monitors that disappear. I don't want them to add or detract from the sound that gets fed into them. Great fidelity on a budget is hard to do, but I'd want to use fidelity as the benchmark, not whether or not they simply sound good.
