I run a Thunder Tiger EB4-S3, and I can tell you that it's a great buggy, simillar to a mugen, but alot cheaper, and tough as nails. It may be a bit heavier, but imo it helps with the handling. You can probably pick one up really cheap too on ebay or something, and Amain has em for under $400.00. Make sure you can get parts, they can be hard to find locally sometimes which is why it's not the most popular buggy out there, cause it sure is one of the best. 2006 world champion!!
