I am pretty sure you will be happy with it.
Read the manual, (skip the marine stuff) and sit home and play with it. They frustrated the hell out of me, until I learned how to navigate the menu's, now it is 2nd nature. Just like the first time you used a computer mouse, it takes practice.
The units will do a lot of things, you just have to know how to ask it to do what you want.
BTW, when you first fire it up, set it in an open area, antenna up. It will take a little while to get a fix, as it is looking for satellites floating around the East coast.
