Re: SF-AW210 is USD 8.0/pcs
First there is no GB-- ATM 
second I am not selling any 6X sleds or diodes( so I have no axe to grind) but.....
 
finding a source is the ONLY  easy part--
 
So before somebody starts accusing anybody else of price gouging I must say this-
 
-A GB is no walk in the park---there is a lot of work, lost sleep,  and risk involved-- I know, as I am currently waiting for 7 PGL paid for mostly with OP $$ and its MY rep and butt on the line. 
 
There a lot of things that CAN happen--  VAT- customs siezure- duty fees- lost or stolen stuff, scams  and so on.
 
The OP says this is for an order of 100 sleds- not 2 or 5 or 10 ... 100!!
 
There is a lot of 'hidden' costs involved in a GB- ones time, handling- packing materials- PP fees-labor etc
Consider gas costs---
pink slips in the mail box or on your door that require you to make a drive to go get the package etc etc.
 
There is always somebody saying
he can get the parts and for  this or that for soooo much less- they
usually leave out a part or two and think  ones labor/time  is not worth
anything-- -very easy to say.
another thing  never taken in to account is the
possibility of a return/repair. shop supplies  , etc and other costs
(labor-rent etc)in China compared to UK , USA, ETC.
 
If a few sleds are defective who covers that?? China? yeah-- they will jump right on that.  Are you going to check all 100 sleds to be sure they are ALL good- didn't think so.
 
So thats my .02+ cents on this thread-
 
SO  flame away -
 
- unless you have been there your OP means little.
 
I have a lot of respect for those who have run many GBs-- thier hard work is way too often taken for granted.
 
 
PEACE-- YA HEAR!!
