Here's the deal...I've got $45.00 in Best Buy credits I can use. They offer a couple of Garmin units. Lowest one is about $90.00, Etrex portable http://www.bestbuy.com/site/Garmin+-...&skuId=9263307 the other one is $120.00 or so Etrex Legend http://www.bestbuy.com/site/Garmin+-...&skuId=7729773 All I need is a "get me home' GPS with local Galveston Bay (TX) maps. Not sure from reading the data whether they include USABLE water maps or not. Anyone here have either unit ....and who would tell me if they will do my simple job? Any ideas or suggestions appreciated. thanks, Rich p.s. I would not be adverse to buying elsewhere, but...I do have the credits to spend at BB.
