I'm looking to upgrade and have been shopping around alot. I came across these two receivers at harmanaudio.com. They're both factory refurbs with a 2 year warranty. They are both selling for $397 and wondering if any out there have any experience with either or how they compare. Both seem to have similar specs so looking for a reason to purchase one over the other. The 335 is the newer model, but the 430 has 10 watts per channel more. Anyone take a swing at these??
