This site is an iffy place to ask for recommendations, as one gets every point of view, including sane ones, crackpot ones, and ones based entirely on preconceived notions. For example, people who say "All XXX speakers are bad" can't possibly have listened to them all, and how do you know what they mean by "bad"? Maybe it's what you would call "good."
On the Steve Hoffman Forums (Google for them), you will find a moderated hardware forum with many practical and generally courteous audiophiles, including quite a few Polk users. Yes, there will be a variety of opinions, but people listen to one another, the moderation tends to weed out the cranks, and you'll find people who actually have listened to the speakers you are thinking about -- and also many other moderately priced speakers.
The present site is great for selling gear, and its forums provide entertainment and at times some good answers to very specific questions. But for someone on a budget asking the question you did, I suggest you try the alternative mentioned and see what you think.
