Anything below $1K, be it pellet, offset, or maybe to a lesser degree a ceramic kamado (egg shaped) grill will need some kind of protection from wind, because steel will be thin and susceptible to wind-chill/heat loss.
Because of your pretty cold winters, without protection from the elements, you would have to spend $2K and up to get an offset with thick enough steel to be functional in your climate.
If you can harvest an oak, pecan, fruit, nut or other hardwood tree every two or three years that would provide some or all of your fuel. While the ease of use of the pellet grills is very appealing, pellets is the only fuel you can use. With the kamado type grills wood chips, chunks or lump charcoal can be used individually or mixed together.
I'm sure there's a lot to be said for the electric smokers, but I have no experience with them. I would be a bit frustrated if our power went out and I didn't want to use the generator's power.
If I wanted to keep my expenditure under $1,000, I think I'd be looking at the electric, like Winelover shows in the picture. Wouldn't be much of a chore to figure out a wind-break to cover 3 sides. Lightweight so you can roll it into the garage, shop, covered patio, whatever, when not in use.
