That's a good price - I got an Nuvi 205 about a year ago on sale for $130 and that was about the best you could do. Yes, it should work well with my maps. But remember, it is not shockproof or waterproof, and doesn't have interchangeable batteries - expect about 3-4 hours run time.
I was just given a Nuvi 1350t and have been putting it through its paces. Some very nice features, and others which I definitely don't like. For some reason, it will not correctly render the LC version of the Map of the Pines. Also does a poor job with most topo maps using the standard Garmin symbols (including Garmin topo). It treats wetland areas the same as water, so it looks like much of the pines is a huge lake! It also renders elevation contours as very thick lines which could be confused with roads. However, the Nuvi version of the Map of the Pines looks very good on it.
One really nice improvement: like the Oregon and Dakota, you can add as many map files as you like and name them anything you want as long as they have a .img extension. So it's easy to have a bunch of maps loaded at the same time and choose between them. Too bad it doesn't correctly render most topo maps.
