I started checking and noticed from some posts even from this forum that the prs-650 has became a scarce product these days.
Just today i checked the Chelsea center on-line and, I'm not sure if it was an error on-line or if they found a unit laying around, it was re-stocked, and 30 min later out of stock again.
So, if anyone can point me a store (pref. around Piccadilly area) that might have it still available I'm very very thankfull.
