The DR70D is inexpensive but some have had issues with it, mainly not buying or using approved cards. We have been using a TAscam DR680 mkI for about 8 months now and really dig it. It is about twice the footprint as the Dr70D, but prolly a bit smaller than the FR2LE. Main advantage over the 70D is 6 channels, but only 4 XLR, the other two channels are balanced (TRS) 1/4 inch. Uses SD cards and has been solid for us so far. We got ours used in the YS for $325.
I don't have experience with the Busmans but many folks here like them, so the only mics I could rec are any set of AKG actives, prolly find some used although they seem to be getting "rare" to find. There was a Custom Neumann SKM-140 / Naiant PFA Rig chopped for active use in the YS, but over your budget ($1,400) . Would be awesome set up though. (not affiliated)
Whatever it is, get out there and record some live music!
