Costco were clearing the Tosh 52wm48 for a tad over £1000.
The 46wm48 was well under £1000.
That was a few weeks ago, may have sold out by now. Worth checking.
Can't remember what the result of the 3 year warranty issue was on DLP's at Costco. TV's get 3 years free, LCD's and Plasma's dont. Some members got 3 years free with their DLP's others didn't, if I remember correctly. Seemed to depend on the branch and the product knowledge level of staff.
