I think costco has some good ones. I dont know if they are only three hundred though. The cheapest place that we found for the one we wanted was an online seller in alberta. The ones with street map capability are more than the basic ones.. and you ahve to buy the software for the driving maps. The one that I had, was 850 and had teh maps for the BC coastline and Southern BC. It was more expensive as well because its portable, waterproof, and can work through trees.. so its good for hiking in the bush. You can get bigger screen ones for cars, that speak at you as well ( I HATE things that speak to me, I would eventually kill it).
I can look into it if you want.
