I have a 480 and it's just been bombproof....I've never done anything to it and has well respected made in North America build quality. The 8" may be wider than you're going to use often, but the wider head lets you skew stock as you run it over the head to help deal with difficult grain if you need to. I vote 480 and deal with the head down the line if you want to. I put a Byrd head in my 480 and it was not that expensive or difficult.
