I had the Hobbico digital and gave it a toss, I also have there cheap little analog and I have the digital ACE from Horizon, both of these work great. If I needed a new one I have used the combo volt meter/tach from Horizon and it's really a pretty nice unit, the Tach even shows the same RPMs as my good TNC Tach, the volt meter is on with my other two also. Not a bad unit for the price.
