I have a Colorado 400t that I've been using for the last couple years. After 4,700 caches it's getting kind of beat up, so I was ready to replace it. I thought I wanted the 62s or 62st, but after taking my Colorado to REI so I could compare them side by side, I decided I didn't like the smaller, lower resolution screen on the 62 series. I then thought about getting the Oregon. But I've borrowed my girlfriend's Oregon 550 for a couple trips, and didn't like it as much as my Colorado. I'm hooked on the rock and roll thumb wheel for fast, single hand operation.
So I ended up buying a brand new Colorado 400t, keeping my current one as an emergency backup. They are now clearance priced, so it cost much less than the 62s or 62st, and less than half what I paid for my original 400t. Plus I figured I'd better buy it now before all the new ones are sold out.
