Title: DBU and DMC

(Lego: "Methylation with DMC and DBU as base", Novel Discourse), can anyone provide some target prices for DBU (1,8-Diazabicyclo[5.4.0]undec-7-ene from the article, not the nonene analogue in Lego's voice which is actually DBN) and DMC one might negotiate for when dealing with asian chemical companies?  I was unable to find any prices for either of these when googling.  Would importing be the best way to get small quantities, say < 1kg of the DBU and < 3 kg of the DMC (I imagine importing less than that wouldn't be economical), short of having an account with a large chemical distributor?  Any advice is appreciated.

DBU should be available for < US$200 / kg
DABCO (which is another relatively interchangeable strong hindered base) < US$60 / kg
