Yeah, not more than 2 weeks after I ordered mine (in May) they disappeared from the website. I don't know if there are any still left in the stores, but if there are...they are probably the last ones in the pipeline.
We ordered ours from Costco.com since we didn't have a truck big enough to get it from the local store to the house, and with free shipping from Costco.com it was much easier (and more cost effective) to have them worry about getting it here. We got it 10 days after we ordered it, and with the convenient handles on the side, moving it to its new perch wasn't hard at all.
LOVE this plasma. No problems with it whatsoever. No buzzing, no picture problems, no image retention, no problems at all. Just pure, glorious 58" Hi Def goodness. And an incredible value for the price.
I still need to some tweaking of the picture and color settings since our HD cable channels look warm whereas our SD cable channels look cool...so I may add one of those video calibration DVDs to my Netflix queue.
