> Atgbics SFP+s have been a reliable clone supplier for us.
With the caveat that I'm a USian and my scale is even lower than yours (10 10gbit SFP+ modules in my apartment combination home, office, and lab, running trouble-free for the past three years) I've found 10Gtek to be a reliable supplier. You can order 10gbit SFP+ modules straight from them for 14USD per per module. Though, shipping costs straight from them is currently pretty terrible: $35 if you're spending less than $800.
Stores like Newegg will often meet or beat that per-module price and offer free shipping if you buy a bundle of four or more... but modules with the personality you want may not be in stock.
