DJ Speakers for home use small room

Hi, I'm looking for some advice or suggestions on what kind of monitors to buy for my turntables for use in the nearfield. I've looked at Alesis, Event, and other brands geared specifically towards the professional studio, but something tells me that I can probably find something better at the same price or even cheaper than the 'mainstream' brands and models.

I need something that'll have a good punchy bass response and clean highs. I'll be listening to them from no more than 3' to 5' away, and my bedroom is very small so it doesn't take much to fill the room with sound. I am willing to buy a used pair, and do not want to pay much more than $300 including shipping. Can anyone give me suggestions?

Also, I'm going to need to buy a decent amplifier...I'd be looking at the 250-300 price range for that as well.

Thanks for any help.
