Actually look around and you should be able to beat a hundred bucks, particularly if you go for the more plain looking V67M instead of the snazzy green and gold model.
You might be able to spend a few dollars more, but you might be able to save those dollars and still be happy with the results.
If you cannot find a store with a generous return policy buy one on ebay and if you don't like it sell it the same way.
Actually, it's going to be pretty hard to find a V67M, since that was made specifically for Mars Music, who is long since out of business. The other models are the V67B (often just called the V67), and the V67S. The only difference between them is the body color: G = green, B = black, S = silver. You should be able to do better than $100, probably in the $80 range.
I have one, and love it. I'd highly recommend it. BUT, I'd also recommend spending some time with the mic you already have, to make sure that what you really need is a new mic. Sometimes, you need to work with mic placement. Try it at eye-level, pointing at your mouth. If that sucks, try it at chest level, pointing straight into the chest. If that sucks, try directly over your head, pointing into the middle of your cranium. You get the point. It's not always about the gear. In the end, it's about the sound, not about the gear you use to get there.
That being said, I have seen many folks trash the Behringer mics. I've never used one, so I have nothing to say about it. If, after much experimentation, you decide that the mic has nothing to offer you, and of the mics suggested above would be interesting starting points. Head down to a store, and line 'em up, and give 'em a test drive. See what you think.
