I satisfied my urge to have my own F/J seat by buying one of those Panasonic massage chairs just before Christmas. Not quite a skysuite, but believe me it was one of the best $4K I've ever spent! And every guest I've had to my place since then has concurred.
Of course as SQ converts over from the older F suites to the new ones, they might be willing to sell you one...as long as you could live with the old version.
