i second alpkit,
http://www.alpkit.com/shop/cart.php?...ategory_id=253

i just bought their little nipper, only a touch smaller then their adult small pad, a good bit cheaper...and has a warmer rating ! ( i am a bit of a gram weenie ! )

great customer support, and a great pad.

also, youtube various pads you might find, there are some good reviews there.
to me, the neo air is a bit noisy !
