I prefer the 4 x 8 as well but it is getting harder to locate and quite a bit of a price difference. I can get a 60x60 b/bb grade for $32 and the 4x8 is ranging from $49 (if they have it ) to $70 per sheet. I have noticed the suppliers like to quote the lower price when out of stock, but when they get it, it conveniently had a price increase.
