I have seen those sites, but Ive never bought from them personally. Make sure to take a good look at the product picture, not just the anime icon they have posted for the costumes. Sometimes the costume has a few slight differences from the character that would have to be adjusted after you get the costume. I do know of one site that does amazing commissions, but she's not cheep... Shes well worth the cash if youre commited to cosplaying the same character for a long time... Limebarb.com... And MAD props for wanting to cosplay Gene Starwind!

Expensive stuff, you may be better off finding a friend or something that's got a bit of talent and getting the material and making it yourself. The outfit doesn't look like it would be too hard to make.
I just got a quote, $275.00 USD, AND I have to buy the bodysuit and pants on my own and send them to the tailor to modify.... I'm going to quote around a bit more, I have until october so I'm sure I can find somebody with a lower price....
This is the best gift I can give you for now, the gift without form called Memory. I have no money, I cannot buy you much with form. Even so, Memory will last Forever!
