I have a PB-3 -works OK with the Android interface - I just bought an el cheapo mobile and use that.

I recently borrowed a Dynavibe to balance my prop. It worked well and I am looking to buy some type of dynamic balancer. Firstly, does anyone have any experience using the UK PB-3? They are about half the price. One negative is the use of an android interface with wi-fi. Also are there any used Dynavibes out there for purchase?
