Up-front cost is $65, with an extra $10 per license renewal (which is every 6 months). Really not too bad if people actually plan on using it. Plus, we have $75 in credit already anyway and license renewals are optional, so I tend to let them lapse between major security updates.
I mean, i'd rather host here than photobucket, but I rarely have images to host these days. So it's a bit of a wash on my end.
