Tabdog ... thanks for the insight ... I did buy the Triton 1500 (closeout price of $186 .. original price was $469) but ended up taking it back when I discovered it didn't contain the map package like the clerk said it did. Knowing that I can always take it back, I ended up getting the next best deal (and probably the best deal anyone could ask for) which was the Triton 400 Adventure Pack ($175) which contains the National Geographic TOPO Explorer map pack, 25 credits for getting 1:24 maps, SD card and carry case (easily a $100 worth of goodies) ... Ironically, they also sell the Triton 400 without all the extras that I mention for the same price (now there's a deal that won't be flying off the shelf very quick).
I've never owned one before so I don't know what to expect in terms of performance though this seems to work just fine ... I was setting it up last night and all was working well ... the software seems a little buggy and doesn't auto load like its supposed to ... a bit annoying but not a major obstacle ... my next challenge is to figure out how to get the maps loaded into the GPS unit itself.
For anyone thinking about getting a Magellan I can tell you that it doesn't come with a lot of documentation so be prepared for some trial and error. The only significant differences between the 400 and the 1500 are the number of waypoints it will store ... also the 1500 has a larger screen, a touch screen and a built in flashlight which isn't very bright.
