Steven,
What you're asking is a very reasonable question, and has been ask here a thousand times. Unfortunately, there's no really good answer of the type of answer you're looking for.
In your price range - indeed, in ANY price range - there are going to be many models, most of them will be of pretty solid construction and decent enough materials. No two of them will sound the same. Here's the rub:
The natural question then is which ones sound "best". Ask 100 users and you'll probably get 110 different answers to that question

. The problem is that just like no two loudspeaker models sound the same, no two human models hear the same or have the same hearing preferences. One person's "flat" is another person's hyped and that second person's "flat" is the first person's midrangey. Complicating that is that there's little agreement among perfectly good engineers as to whether flat, hyped, midrangey or something else actually helps or hinders their individual ability to coax out good-sounding mixes.
Hopefully you have two things going for you; that understand your own ears and hearing well enough to be able to judge for yourself what sounds "right" to you, and that you have some showrooms (both pro audio and home audio) that you can go to with some of your most familiar-sounding CDs and listen for yourself. This is not perfect, as the showrooms themselves will affect what you're hearing, but it should get you close enough.
And when you do this, make sure you're working with a salesperson and company that understands your situation as described here, and has a reasonable exchange policy, since you'll explain to them that you won't really know until you get the speakers home whether they'll work for you. This is equally true of any Internet or mail-order sales places.
If you really don't know or can't tell what sounds "right" to you, then you've got far more problems ahead of you than just choosing speakers (

). Then you'll have little real choice other than just gambling with what looks like the best deal and best sound, and getting them home and and simply learning how to mix with them; i.e. getting you ears used to those speakers rather than getting speakers that naturally suit the way your ears are now.
