I'm also considering getting the LG 42SL8000 or 42SL9000 (waiting for review with avforums)
The best place so far to get the SL8000 is at digital direct as they offer a 3 yr guarantee with it for £949
LG 42SL8000 Full HD 1080p LCD Television with TruMotion 100HZ and built in Freeview - in stock at Digital Direct order today for a free 3 year warranty
Its a great TV, can't wait to get mine
