looking for something that I can get a couple of for relatively cheap to hook into boards at some of the festivals I attend. Ideally would be 32 bit , and have XLR/TRS inputs. Right now the Zoom R4 looks decent for that purpose, but not sure if there is anything better than that for the price. Looking to acquire 2-3 of them so I can leave them at different stages. Hauling my mics between stages can get a bit tiring, plus a lot of times sets overlap.
Zoom F3
Tascam FR-AV2
^ Both are current and proven to be very good for that kind of thing
Of course there are others, including plenty of legacy 2-ch SD card recorders with XLR inputs, and some new ones not yet released or less tested
Many (most?) modern 'boards have slots for memory sticks. Those are cheap, but you need to make sure that is a possibility.
Zoom H1 XLR if 2 inputs is enough?
