I can certainly vouch for sizzus. The whole transaction was instant and took literally minutes. Definatley reliable. £30 for 320k with ea tax covered is a fantastic deal and I shall certainly be recommending sizzus to everyone I know.
Ah I had forgotten about Sythe!
The best way to get in touch with me is via Skype (Sizzuz). After I've accepted your contact request, send me a message and I'll reply when I'm next on and available to sell coins.
I see one or two impostors popping up on Facebook; make sure you don't get fooled by these guys. Skype is the safest way to go.
