TV7512 is a good diesel option too for moderate engine size power.

The thing is with the TV's is they are REALLY big/heavy, old technology, and came in LOTs of variations... so you just have to know what you're getting before buying.

Viren (VS racing) is obviously getting his stuff from overseas like other distributors, but I have to say working with him he's a very good/honest person. Not a guy I'd be afraid to buy from. His S480 knock offs are about $50-$100 cheaper then the real thing, BUT come with a billet wheel too. So it really depends how good the billet wheel is if you want to risk buying one. Really too new to tell how much better they are then a regular cast wheel S480.
