I'm seriously considering an SM-900. I've seen what look like good deals on the older model, which according to SWR was in production from 1991-1999, at which point they made cosmetic changes, added Speakons and upped the wattage a bit. OH, and the list price too. Does anyone have an opinion on these older models compared to the newer ones? Am I doing good to get an old one in decent shape for, say, around a thousand, or would I be better off waiting for a used newer model to come up and grab one of those? Is there some reason to think "they don't make 'em like they used to" with SWR? Any help would be greatly appreciated!
