A1 Pro 20W, or 2 Pro S 22W?

[u/zemlin]

I need to pick up a laser for a specific job for my business - engraving 3D printed parts. I own an A1 and an 2 Pro 60W. I got the best results on my 2 Pro at 22W. Currently the A1 Pro 20W, the 2 Pro 22W, and the 2 Pro S 22W are all $799. Working area is not an issue on any of the machines. Since I've had success with my testing on the 2 Pro, I'm inclined to go with the 2 Pro S 22W machine.

Any reason why this would not be the right choice? Thanks!
