Yes, this subject has been beaten to death and many will offer an opinion. I use a Nuvi 550 and am very happy with it. Others have 60cx, 76cx, 276, etc. I've read that the first generation Oregons had some problems, but apparently the newer models have been rectified, can't comment though.
What you want to look for is a unit that is waterproof, like those listed. Personally, I stick with Garmins due to the available snowmobile and topo maps that are free.
