I;ve had good luck with them, for parts at least. Last month, I bought 25 16 pin IDC (ribbon cable) connectors. $5.50 + $4.00 shipping, arrived in 2 weeks. They would have cost ~$30.00 from Mouser.
I had them make PCBs for me once (6" x 5.19" qty 2) but when they arrived they had no silk screen. They were just prototypes so I didn;t complain. They were fine otherwise.
Here are my notes on Futurelec:
http://www.futurlec.com/index.shtmlLimited selection, amazing prices, long ship times from Hong Kong, good service so far, no minimum order, Hard to communicate with sometimes
If a part is out of stock, they say nothing, just don't ship. I asked after 2 mos, they subbed parts and shipped the next day.
Bought 1/10, asked 3/28, shipped 3/29 (Saturday!) Arrived 4/15
Bought 5/22, shipped 6/4, arrived 6/17
