I see mentioned a 2gb limit on Wave,but Neuros units at soundproffessionals specifically say they can do a 4gb wave-my guess is if they can-probably Edirol's r1 can too. The R1 base price is reasonable-but you need to add in the CF card. Obviously a $500 pre and a $500 AD/DA won't be in your sub-$500 shirt pocket size recorders
