Thanks guys!
majphill - The mapping feature is the bestest reason I picke those models and from what I've heard and read garmin has the best GPS units!

I'm leaning a little more towards the rino because of the 2-way radio features. I like the fact that it will show the location of any other rino users, that could come in handy, for hunting! I have several buddies that have rinos, so it seems like a good fit!

Does anyone have the Rino 530 Hcx? I like to get some recent feedback! I know they had some problems when it first came out, but they usually address them pretty quickly!!! Any thoughts/comments?!?!
Thanks
