Yes, Yes, No and then some.
Yes the 96 SHOULD be able to follow the DE TRS after rebanding, other areas have had success with this, there are threads here that outline what is needed for programming.
Yes the 106 will follow DE's TRS now and post reband, no problems.
Nope, no scanner can follow Chesco's crazy system.
The 106 is a pretty nifty scanner with some new features, but the 96 is and should remain a rock solid unit. The current deals on the 106 make it very attactive, I just ordered one to keep my 96's company.
