I do have a recommendation for you in terms of your Wireless woes with the unlimited access plan. If you have a unlimited plan for your phone you can use it as a hot spot. I took a break from my field and did Over the road trucking for a while, wanted to have internet on the road. I saw the aircard and the limitations with that. I also had a Iphone with unlimited internet, however if you wished to tether it, it was a added $10 charge and you only got two gigs.

So what I did was jail break the Iphone to teather it myself for free, and it used the data from the phones unlimited plan. Perhaps you can do something like that?

What about Dish's?
In 2001 high speed internet still wasn't available for where I was living for a time. So I purchased a DirectPC dish. I wanted to share that experience with you, in case you have thought about going that direction.

Again this was back in 2001, things may have changed quite a lot! But here's my experience.

$75 monthly cost
114MB download limit a day
Basically what happens is if you perform say a Windows update, mid way through you reach your 114MB cap which is referred to Fair use Policy. Your connection is then scaled down to 56k. However it was more like 28.8.

On-line gaming ping is so bad it's unplayable. I'd use dial-up to game, much much better compared sadly.

A friend and I both bought them and installed them. I disconnected mine and went back to dial up in three months, he lasted about 5 months.

If your just surfing the internet, might be a good fit. If you want to watch more then, say 4 short youtube videos, not a good fit.
