pmboyd,
Check the head-fi forum. It seems that many are ordering these and there will be probably more reviews soon. I`ve seen only one used Ares and it sold for the new price within a day or so because it was already in US. It was sold because owner wanted to go up in Denafrips line.
Gungnir
Multibit has also created a lot of fuzz so it may be something to consider also. Metrum Hex seems also interesting.
Good Luck!
