I have the Oregon 450 w/sd card and have been very happy with it. I've had it for a little over a year with no issues. Much more user friendly than my old legend hcx.
I just did a ton of gps research for a new one for myself. The only thing I read bad about the Oregon was battery life supposedly sucks.
I picked up a Gpsmaps 62stc for 250 at REI over the weekend. Thats half price. You might be able to backorder it off the website? Sale ended today
I think most will work with the card, although I haven't put my card in yet to try? As long as it will accept a sd card I think your good?
