Hi Jim,
I recently purchased a TS-B2000 and believe it is the best radio bargain out there for $1300.00. I have never owned a 756 Pro so I can't speak about that rig but I know it has legions of followers. I can tell you that I am a computer kind of guy too and the TS-B2000 fits the bill nicely for me. I run the ARCP 2000 software from Kenwood and it works very well. I recently bought TRX-Manager and also run the rig with that too. It is a great integrated package with logging, packet support, DX cluster support and etc. There are more features to this rig than I have been able to explore in the month and a half I've owned it. The DSP work great, good receive on HF and VHF (I haven't tried UHF yet, but spring is almost here!) The RC-2000 remote head gives you all the features of the real front panel on the $1600 version so I say go for it. I'm having a ball with mine.
