The biggest thing I'd worry about buying used Maggies is the barely adequate factory packaging. IMO, it leaves the speakers vunerable to shipping damage. Admittedly, I've had worse than average luck with every shipper out there, but I don't think I'm being paranoid. I'd prefer to pick them up myself if there was any way possible. I can't say I found Maggies to have a small soundstage if they were set up properly with adequate room. As long as they were around a third of the way out into a decent size room room and had at least four feet on each side, I thought that bigger Maggies have a very generous soundstage. We've all got different perceptions about these things though. Your rooms footprint is a good size, but eight foot ceilings aren't ideal. About the only thing to watch out for is delaminated membrane wiring in older models.
