It was rediculous. If you need real data you cannot pay time with a system that is not designed for data. You have to go with data rates, not voice rates.
It would take me 83 minutes for data that can't be compressed or 18 minutes theoretic maximum throughput which brings it to $30 to $145 to download a MByte.
So yes, if you need to download files or similar on a regular basis then it makes sense to get IOP. If downloading only now and then I would still do it on Winlink during the quiet hours but I'm crazy.
p.s. on Winlink, there's so many stations on so many bands... I never had trouble finding one with decent propagation for say 18 hours a day. From the Caribbean
, Canadian stations are my favorite backup, so a south to north path, not crossing night/day borders.
