FWIW, there is an "unlimited data" hack to the jetpacks, you can only go up to 3G service (no 4G) when using the hacked jetpacks but it's cheap ($5/mo). This is my only reasonable (less than $100/mo) internet option where I'm at and I love it!
You want to search out "flashed Verizon jetpack" on ebay. From what I understand they flash the jetpack to appear to be an old dumb-phone so Verizon's network doesn't monitor data consumption, because you aren't using voice or text, and data is unmonitored it looks like an unused phone on the network and you simply just have to add $5/mo to the phone account to keep the line active.
ETA, slowest speed I've had (it was slow enough to make me stop and run a speed test) was ~500 kbps, fastest I've seen is 3.1 Gbps. So you have to be ok with slower speeds, we're able to stream Netflix with minimal problems however.
