Finally tired of lugging amps and struggling balancing big amp sounds in tiny venues. I need to update my old Digitech RP-6 and buy something similar with good clean sounds and an excellent emulator so I can plug stright into the PA and still get a great miked-amp sound.

There are soooo many units out there so I thought I'd ask the question here. What should I be looking at? What are the best buys?
