Which buggy to convert?

[2FastSS4U]

Well guys, I'm ready to take the leap to convert an 8th scale buggy but I've no idea which one and what are the pro's & con's of converting each are. I'd like an easy conversion with minimal modifications to the buggy and still keeping its durability. Basically I've singled it down to either the Team Associated RC8, the Xray XB8, or the Losi 8ight. I'm going for complete insanity on this project something like a 1515/1.5d possibly with a Quark Monster Pro 125b on 5s for the power. Any input on any of the candidates is extremely helpful in my decision making, and if you've got pic's of your conversions please post, I need all the help I can get . Thanks for you time and help.
