I agree with victorcharlie the Garmin Legend is a good deal. It has a good basemap for general travel. Plus you can load up to 8MB of mapping software. It only stores maps from Garmin's MapSource products.
It's downside is that reception in heavy oak or bigger timber is limited. You need to find daylight. I use a combination gps and handheld compass at times.
The Legend package comes with a pc cable. You can upload and download waypoints and tracks from other map vendors. You just cannot load their maps on a Garmin product. Unless you spend the big bucks for a Garmin PDA/Gps. Many times I have had my Legend setting in a dashboard cupholder, connected to my laptop using Garmin Software or Microsoft Streets & Trips displaying my location. I let my passenger do the navigating, and I do the driving.
The price at the gps store is to high. There is one or more Internet Vendors that are selling it for $149.00. I have also seen it advertised for $149.00 in the newspaper as a sale item.
I must admit that I do not always understand gps units and reception. The other morning I took off on a hike into a location for which I had installed the Lat/Long on my two gps units as waypoints. The path I took is tightly surrounded with Oak canopy and tall conifers. Within fifty feet the Legend lost its satellite lock. The 76C lost a couple of satellites but maintained a lock on 3 or 4 depending on the location on the path. Once I left the path, the heavy cover(jungle) blocked all reception on both units. When I broke out of the cover and obtained some sky reception came back. The kicker was the Legend had better reception then the 76C.
In semi open areas, and travelling the Interstate they have the same reception. When I am in those areas I am not at a disadvantage with the Legend when it comes to reception. There are other features which makes the price of the 76C worth it.
I have not used Lowrance gps units. I would check other sources for price. Reading the specs on the unit you are getting a lot of gps for the dollar. Some advantages are the ability to load a lot of mapping information on to the MMC cards. An external antenna outlet if you need that down the road.
Lowrance processors are noted for their speed.
A big disadvantage of the Lowrance Basic it is not WATERPROOF.
It comes with a water proof case. Newer model Lowrance units are waterproof. The price makes me wonder if Lowrance is phasing out this older model because of the lack of waterproofing?
The price at the gpstore is about $30 LESS then what I recently seen at a local outdoor store for the iFinder Basic. :-)
