UPDATE: Read our hands on Garmin Oregon 650 review.
It looks like REI.com has beaten everyone to the punch, and is now shipping the Garmin Oregon 600 and 600t. GPS City anticipates having them next week; Amazon usually lags a few weeks behind these guys. A lot of folks seem to be excited about these new models; perhaps you can see why in my post on the Oregon 600 series.
REI looks like a good place for early adopters to buy. They’ve got a great guarantee if it turns out you don’t like it, free shipping on orders over $50, and members get 10% back on their purchase (that’s $40 for the Oregon 600 and $48 for the 600t). A lifetime membership runs $20, so it will cut your price to sign up when you order.
I hope to have a review unit in the next week or so.
