Here is another you may look at.

I am thinking of ordering one in the next few days, possibly today. I was not fond of Skycaddie for the paid courses and lack of available courses in my area. Check their site, if the courses you play do not have a 3 to 4 star rating for download, it will only give you Front, Back and Center of green. There is only one course in my area out of about 40 courses that has more options, and that course has sense gone private. Plus I play my home course the majority so I will likely enter it in with the 8 other points.
A range finder is another viable option for around the same price, if you do a search on here you will find some links with interesting comparisons.
