Just to give you an idea of what's out there, you could check the Stereophile Recommended Speakers page. I frequently found that I would choose a component and some time later they'd review it and endorse it. There's a lot of BS in that mag, which is why I stopped subscribing years ago, but you can at least get a general sense of what speakers are considered a good value.

(stands necessary)
"The Audioengine 5 powered speakers come packed in attractive cloth drawstring bags, and include several convenient accessories: an AC power cable, miniplug interconnects in length of 2m, an RCA cable (2m), a 3.75m length of simple speaker cable, and a remote control. Each A5 cabinet is made of 25mm-thick MDF, measures 10" H by 7" W by 7.75" D, and houses a 20mm silk-dome tweeter and a 5" Kevlar-cone woofer. The left speaker enclosure contains a 50Wpc dual class-AB monolithic amplifier, as well as the power button, volume knob, iPod charging port, and IR window for the remote. Compared to the PSB Alpha B1, the Audioengine lacked some high-frequency detail and delicacy, but offered outstanding bass control, transparency, and drama, said SM. Price is for satin black and high-gloss white finishes; bamboo adds $70. (Vol.34 No.5 WWW)"
