I'd choose the Mugen too mainly because I drive a Thunder Tiger S3, and they are quite simillar. The TTR s3 could be another choice too btw, I'm gonna get flack for this post. lol Here's a pic of mine, I have alot of time to upgrade it here in Canada, winters are loooong!! If you can get parts for it I would definately recommend it. If you shop online, parts are easy to get Amain hobbies, thundertiger4u, etc.
