I came across this site NiceDiaper.Com which not only has a fascinating selection of products but lists improbably low prices (in $US) - but a quick bit of googling suggests they are legit, and these prices are not based on wholesale volumes (which was my first guess.) Some feedback was here: Diapers From "nicediaper" Company In China - DailyDiapers Boards & Chat
(Though it appears that net cost comes out higher than the advertised price on NiceDiaper.Com due to shipping/handling/customs, (I am guessing.))
Among their product categories is ABDL - so they are ABDL-aware: a good sign.
Here is some of their eye-candy, including fascinating asian diapers with an ultra-low crotch (sumo-style)
Update: there's an ADISC thread: http://www.adisc.org/forum/diaper-ta...4-yuyun-2.html silly me, first place I should have looked. Yeah, their prices are low-ish but not drastically lower than the usual suppliers where I am... Here is their Canadian ebay store Shop eBay Canada Store - YUYUN:: Adult Baby Diaper, cloth diapers
