Conversion Lenses and Crystal Optics Filters

[Photoholic]

Just a couple of questions concerning the above items. From what I gather around the internet, these conversion lenses, screw on the end of your lense for the desired effect. This doesn't seem like it would be very good quality...am I wrong? Also, Crystal Optics brand Filters, how would you rate them? Any other brands I should look at? Overstock.com has them ranging in price from $19.99 - $36.99 for a set of 3. They're usually a lot more expensive, was wondering if that was a testament to their quality... Any help is very much appreciated!! Thanks!!

Well I am curious now too, so will see if a bump up will get you a response. I have no clue either.
