Cheapest place to buy iPhone 4 Conversion kit?

Looking for the cheapest iphone conversion kits , reliable + reputable seller for a iPhone conversion kit. any color besides black.

I cracked my screen, and the replacement LCD is $80.. so why not spend a couple of extra bucks and just convert it to white!

any sites you guys recommend that sell it for a good price? if it's good quality i'd be interested in purchasing more than one kit.

someone on the forums recommended Slickgate on this forum.
The white one just costs $47.98
is there anything cheaper? thanks.
