I have experience with the 76S (Score 1)

The 76S has been in my hot little hand for a while now, and I did a fairly indepth write up on it here. As others have said, the eTrex is alright but far too basic for you. I recommend the 76S, it's a great receiver if slightly lacking in battery life. HTH.(and the opportunity for self-pimpage is welcomed :))
