PS for a supergood value i just spotted their BASECAMP model which seems beloved by users
http://www.cascadedesigns.com/Therm-...seCamp/product
list price is $90 so i'd expect it at amazon for around $70.
actually comes in R, L, XL so 3 widths = 3 prices
but it's only 2in not 3in (or 4). still could work well.

$80 FOR THE XL

(hey, i'm doing this research for myself too)
the BIGGEST luxurymap is exactly double @ $160

(the regular is only $90)
