Three guitars is probably ideal. One really nice one to play alone or with good (and sober) friends in your living room, or in concert settings with excellent acoustics and everyone really listening (if you're lucky enough to ever get to play in those circumstances; one "everyday" gigging, party, singaround, etc. guitar; and one beater for wandering around in the rain, half drunk, and tripping over tent pegs at festivals (actually, I don't do that any more, so maybe I only need two).

That being said, I now own:

2008 (?) Manuel & Patterson 00-12.
2002 (?) Apollo jumbo 12-string.
Late 2002 / early 2003 Huss and Dalton CM Cutaway. (Essentially an OM with dreadnought depth and soft cutaway.)
2007 Rainsong OM1000.
1996 Collings 000-2H.
Alvarez-Yairi Jumbo Baritone Acoustic (now for sale).
Trinity College Tg-202 12-fret Cutaway 000
"The Loar" LH200 small-body sunburst (now out for repair after the bridge cracked. Probably sell it later.)
1970s Guild D25M (kept in Bozeman, MT, to avoid having to carry a guitar on the plane).
Guild M20 Reissue (early '00s).

I am astonished that anyone could complain about the power of the Rainsongs. My OM is my basic gigging guitar, and I can make it heard pretty much anywhere, all across its range.
