Need GPS advice

[Shawsee]

Hi guys,

I am in need of GPS advice. I will be purchasing a GPS soon and my budget is limited. I know there are GPS units that are really expensive and I am wanting just a basic unit that wont cost me an arm & a leg. I was wondering if those Garmin E-Trex are any good. They are reasonably priced but, would it serve my needs on the ocean? So I am asking you experts because this is still all new to me. I just don't want to buy something that wont serve the purpose and needs, while on the other hand I cannot spend a lot of money right now. Later on (next year) I will upgrade but for now cheap is the only way. :-/

Thanks guys.
