Thanks for the feedback you guys. I've been thinking that I could go with a built 700R4, but wanted to check all my options, so Gear Vendors was a good website for me. It looks like a solid unit, and I'd love to keep my T400, but the price tag is a lot higher than a Raptor Level 3 kit for an R4, and the Raptor kit should hold my motor OK. Not crazy about the lower gear ratios in the R4, but I'll be doing more cruisin' than foot-stompin' (I'm getting old). Thanks again for helping me out!!
