That is super helpful info! Thanks so much!

Hi Claire - I used to rent them from a place in Florida called Satellite Phone Solutions.  As of two years ago they had the best price I could find, and I found the service to be very good.  They fell through once when a hurricane shut them down (excuses, excuses), so I had to buy one.  The problem in renting from them is timing - they'd be shipping to Canada, and predicting accurate delivery dates might be a little dicey. 

Spotify also rents them, but I think the issue is the same (predicting delivery time).

I just found a Canadian company that rents them, Avantura.  I don't know a thing about them, but that would overcome the delivery problem.

I wish I could offer you mine, I'd be very happy to send it up for you to borrow, but I don't know when I'll be tripping this coming summer.  We'll probably look at summer schedule fairly soon, and if that timeframe looks open I'll certainly drop you a line.
