Romad,
There is a used LS28 SE up for sale right now here on Audiogon for $6,500, but willing to accept offers. It was upgraded to the SE version by the factory less than a year ago, and has a new compliment of tubes and upgraded caps. Condition 9 out of 10, seller has a 100% satisfaction rate.....seems like a really good deal, and probably will not last very long
