I'm looking to get some advice from the pros on purchasing a new GPS. I have been caching with my iphone app, and have attempted to use my Garmin Nuvi for some puzzle caches, but I am finding it very difficult, so I would like to get something new before we attend the event in Merritt this weekend. I was looking at the Garmin Oregon 450 that they have in Costco at the moment as I see they are reasonably priced, but it appears that some people have had difficulty with them? I am looking for something that is accurate and easy to use, and that I can load caches onto from my computer. Can I load caches from geocaching.com onto the 450? The package said something about being supported by opencaching.com? Also wondering if anyone can suggest another retailer that carries GPS at reasonable/competitive prices. Thanks.
