Motorola R765 Vs. Motorola DTR/DLR Devices

About 10 years ago, Motorola announced the R765 and R765IS. The “IS” version, Intrinsically Safe, only had about 600 milliwatts on Direct Talk. The non-IS version, however, had a full 1 watt on Direct Talk. I am just wondering if anybody here has the Motorola R765 and, if so, how it compares to the Motorola DTR/DLR devices. One of the good things is the R765 are compatible with the Nextel Direct Talk devices.
