Rich,
I took the plunge last night on a 50PS6000 and a nice alphason apx50/4 stand to bolt it to.
I do a lot of gaming including far too many hours on Rockband so I will let you know what the retention is on my set after ive had some time with it and it has been run in.
I think the only thing to budget for with this model from what I can see is proper ISF calibration if you really want to do the panel justice.
