Hi,
I'm not familiar with Wantai drivers but now they are well represented in the market.
I've seen a number of recommendations for Leadshine's AM882 driver, it is 80V capable.
Gecko are the gold standard when it comes two phase drivers but are somewhat more expensive.
The real trick to buying steppers and drivers is:
1) Buy low inductance motors. 23/24 size motors look for 1mH or less and reject any over 2mH. 34 size look for
2mH or less and reject any over 4mH. Low inductance is as important as holding torque.
2)Buy the highest voltage driver you can get, 80V seems the industry wide max, and then use a transformer type,
preferably a toroidal transformer, power supply of 72V or more.
