The MachTach is compact, works well, and you can program the teeth very easily. I would not know how to modify the $20 ones for the number of teeth, and you might get into limitations of maximum number of pulses per counting period, as the default is 1 pulse (range per counting interval). There are counters with scalers, but at the end of the day probably be close to the MachTach price. I rarely use the SFM on my lathe, but the MachTach would be plug and play. Like the use of a gear tooth pickup on this type of lathe.
