vortex rangefinder

Hi guys, anybody with any experience of either the 1000 or 1500 vortex rangefinder? I've looked through the vortex scopes and was very impressed.
I've had the 1000 for the past year. Very effective, pings the house across the valley at 900m but won't ping trees reliably at that distance. Out to 5-600m it's solid on pretty much anything, which is in line with the specs, at 1000m it would need to be a good reflexive target. I like mine and it's a good price.
