I don't know about Sage but I'd sure like to find an international company that offers a simple and trustworthy bitcoin purchase system and a simple and easy way to sell and transfer back to fiat currency functionality.
I'm searching high and low for such services. So far, all I have is:
bitstamp.net - seem to be slow and not very responsive but, yes, the biggest
bittylicious.com - simple easy low amount purchase in the UK
coinjar.com - Australia.. .New Zealand Coming.... just got $500K VC funding
Canadian Virtual Exchange -
http://cavirtex.com/ - Seem top notch with many buy, sell, liquidate options.
PLEASE Bring on any other suggestions as I have friends and community members around the world who would like to know where to go to find simple, trustworthy Bitcoin buy/sell executions and fiat transfers.
Thanks!
