Having owned the hot-rod, the one you have, and the 350 ref. I can tell you the 150ref is a toy compared to the 350. I know that sounds harsh to a 150 ref. owner but it is true as just the cost might indicate. I have since moved to the CJ premier 350 and latest Rowland 312 and each is a huge step up in resolution.---Don't shoot the messenger.
