Another vote for the modded UA-5.
As an owner of a couple, I can second that. They are a little difficult to wrap your head around, but the search function of this board will help in finding all you need to know about these units.
They are also not easy to find. That does not make them better, its just a consequence of time passing on discontinued units.
Getting a different deck would serve a few purposes and is one you should consider.
A lot of recorders on the market have the clean gain you seek from another piece of equipment.
Minimizing your footprint and the amount of gear you bring to a show is something to consider... because that is important in real world scenarios.
P.S. Responding to old Yard Sale posts can be futile. Been there myself. If you have time to shop, find what suits your needs. If you need one soon, listen to the member's above input in your wants/thinking. Just reading tapers opinions has been the highest rated guide for my purchases in the past.
