Just so you get an answer tonight - if you want cheap(ish) and something that will do the job for beginners - a bit like comparing a commodore with a ferrari - look at the HEQ5Pro - Available everywhere for fair prices and has goto capabilities. Limited on loading ability but it should handle a 6" SCT - if not the EQ6 may be the option
