Go with the jammin pro, you can get it for under $500.00 bucks ,I think GS Hobby has it for 499 as well as Ultimate hobbies. Great durable fast buggy with cheap spares (although you won't need them) I have raced and bashed the daylights out of mine and only wear out spurs and one pinion. They handle as well as anything and turn better then most.

I have seen the Hyper 8 but it was being raced by Paul Coleman so of course it was fast , it will be out after the first of the year so I here.

Ofna is your best bang for the buck or euro or yen hands down!
