When we bough the T38's 2 years ago - they were the only ones with Gigabit ports and a Color Screen. The price was decent. Yealink even customized the firmware for me so we could have Multicast paging and Shared Parks for 3cx.
I am a little disappointed however that they are no longer actively updating the firmware on the T3x series of handsets. I would recommend the T46 instead.
