Not true. An 8x10 is way, way easier to move than two 4x10s. I have two 4x10s. If I had it to do over again, I would DEFINITELY go with an 8x10/4x12.Get 2, 4-10's or 1, 4-10 + 1,2-12
They will be easier to lug around and won't scare the smaller clubs.
As for what I would recommend, find an 8x10 that you like, preferably used. Then buy a Peavey IPR1600 and a preamp. In fact, most pedal-style pres will run the IPRs. I can run mine off of both my Tech21 Bass VT and my MXR M-80. The M-80 actually sounds REALLY good through my IPR1600/Tech21 B410 setup.
From there, bridge the IPR1600 (you'll need to build a special Y cable for it, but it's safe; just make sure you look up the proper configuration for it) and voila! You'll have an easy to move rig for well under your $1400 mark.
