Can anybody really review the WS-1080 and determine if it'd be worth upgrading to a WS-1080 from a RS Pro-106?
Sure, real simple.
1. If you don't have a Phase II System to monitor there is no need to upgrade.
2. If you are concerned about getting repairs done to your Pro-106 then upgrade.
3. If you find that your 20 scanlist limit and memory limit on the Pro-106 is too small then upgrade.
I have both the PSR-500 and the PSR 800. No Phase II systems here and I still prefer the 500 over the 800 and use the 500 as a base unit and 800 mobile.
Bottom line is the sound, sensitivity etc between a 106 and 1080 is negligible.
