I got one from ebay like 4 or 5 months ago, i believe i paid $220 (For the Rocket Fuel). Its a great pedal, my favorite. I also have a Carl Martin Hot Drive n boost, so i compared both.
IMHO, the RF has a lot of gain and is more Tubescreamer-like (if that makes sense...), its not very transparent. The CM on the other hand, is very transparent.
On the boost section i found the RF adds more compression (again, just imo), while the CM really increases volume.
Anyway, both are great but the RF is killer, cant go wrong with that one. Hope that helps.
