That 3910 isn't a steal, but it's a fair price, I think.
I've been extremely happy with my SACDMods-modded Denon, and their prices are much more competitive that Modwright Exemplar et al. You can get a 3930 brand new factory sealed for ~US$1K (that was with 5 seconds of Googling, I'm sure you can do better), plus the SACDMods mods will double your price, will still be well within your price range.
I think Hirsch has a Modwright -modded Denon for his source, and he's extremely happy with it, I think. (And I mention it because his can of choice is the R10.)
