You can get the "High-sensitivity" eTrex now as well. The problem is Garmin will not disclose, at least so far, which chip they are using in the "new" eTrex. I have used the SIRF chip for years in my other GPS units; and you are right, there is really no comparison. I need another handheld backup unit but I will not buy anything except SIRF; so I will wait and see.
