I've got a backpacker. It's ugly, sounds like a banjo, and doesn't ride your leg very well, but I like it. With a roller bag, flight bag, and computer (got to have your priorities set right), it's a bit much to carry the bag along on trips. But for those long reserve stretches in the crash pad, it's just right.
I string mine with a set of electric .09's - which doesn't sound too good, but more acurately duplicates the action of my electric. I have small, dwarf - like hands so the small neck of the Backpacker works well with me.
I got mine off ebay for $120 last year. There are a number of guys who sell scratched and dented ones from the Martin factory for a song. Pick one that has an auction ending time in the middle of the night and you can get the best deal.
Dude, read the sign - no Stairway To Heaven.
