Last week I went to the only bitcoin ATM that was nearby that both bought and sold coin. Had to travel 8 miles, was in use when i got there, so had to wait a few minutes. Then had to wait for one confirmation to cash out(around 1/2 hour) The map showed a few others bitcoin atm's nearby that only sold. It paid at a rate of $3000 per coin, about a 10% discount at the time.
Sounds about right for Bitcoin ATMs, they aren't really anything special and they're typically pretty clunky when it comes to their use. There's one a city away from me that I know of (and probably more within the city I'm in that I don't know about), and the one I know of is pretty bad when it comes to fees/differences in spot prices, and that was years ago. I'd hate to see what it is like now.
It's kind of weird to think about how it's been such a long time since I got involved with the community and the kinds of things I've seen (like the ATMs) that were never really popularized.
