mantis
I have had 3.. reason being 3 is because I alwasy get two.. one to race and one for parts.. I think for the price you cant beat them.. my only complaint was that the parts were not the easiest to obtain thats how ended up with three. im not entirly sure if it was my lhs just not getting them or if they were indeed just hard to get.. but in all fairness i got the mantis when they first came out.. parts should not be an issue anymore...
