Thanks for the positive feedback from all, and especially the link to the acoustics page. There's a ton of very useful and, most importantly, practical information in there!
OK, now that I'm re-assured I can use 'em, the struggle begins to find a decent pair. I noticed a magnificent pair of IIs on E-Bay, but the seller wants 2 grand for them. Seems a little high, especially since the crossovers will most likely have to be re-furbed. And there's shipping to consider. Still, I guess the quest is part of the fun.
Speaking of shipping, are there any good strategies for moving these beasts around? I noticed an old thread about a custom made, armored, shipping container making the rounds of the upper mid-west, but that's not really practical for me in the Southeast. A 1000+ mile road trip is not something I'm looking forward to either. Anybody have any luck with Common-Carriers? Moving companies? Ideally, I suppose, would be to box 'em and strap 'em to a wooden pallet. I figure transportation is going to add 300 to 500 dollars to the final cost, depending on where in the country they're located.
