Suggestions for an affordable (dongle) pendant that will be compatible with Mach4. Connected through USB.

Hi,
I have used a VistaCNC P1A with Mach4 for six years.....it works OK.

The only time I have any bother with it is when or if I push the spindle hard....it tends to interfere with the pendants USB connection.
I've found it necessary to power cycle the entire machine in order to get the USB connection back, a PITA. Fortunately it does not happen
often....in fact so infrequently I've never bothered trying to track down the source of the fault. Maybe my new build mill will be  better, or
maybe worse!
