Hello! I've been really interested in buying one of these for my cnc. I've seen a lot of people using it and it seems that it's a really reliable stepper driver. Now I got a few questions, first off, does anyone recommend it and are there any superior specs that make it particularly outstanding (would you recommend something else)? Is there a difference between the "t" model and the "a" model? And is there any reliable distributors one would recommend?(reason being, I impulsively bought 3 of the dm542t from a sketchy distributor and had to get a refund from Amazon).

Thanks so much in advance!!!
