Ebay wheels?

[onefastz]

This may have already been discussed in an earlier forum, but I was just curious if there is any harm in purchasing new wheels off of ebay? I guess I'm just hesitant in buying wheels that are listed as buy it now for so cheap, does this mean the wheels are just cheap wheels? I do not want to buy wheels that won't last, yet I do not want to spend thousands of dollars. Here's a couple of examples of what I'm talking about.
18" Rota Wheels 18x9.5 Torque GM G35 370z G37 Genesis: eBay Motors (item 270591649057 end time Jul-09-10 21:41:25 PDT)

18 XXR 522 Concave Black Wheels Staggered G37 370z 350z: eBay Motors (item 220628101452 end time Jul-05-10 22:41:11 PDT)

20 XXR 521 BLACK RIMS WHEELS 350Z 370Z G35 G37 G37S: eBay Motors (item 300431411094 end time Jul-25-10 11:10:06 PDT)

Are Rota, Tenzo, XXR, any good? I'm simply trying to find a decent, quality set of black wheels that look good for my Z around the thousand dollar range. I know it's probably impossible, but it would be great to find some 19's or 20's with a tire package for $1500 or less. Does anyone know any good websites or have any advice for me about these wheels, or does anyone have anything like this I may be interested in?
