Worth? There is one on here for IIRC, $250.

Is this the one you're thinking of?

I saw it but don't know what the difference between a TR5 and a Street Ram is? I have been looking for a year or so for a Street Ram because I read that they were more suited to street use? Are they the same? Am I missing something?
