I bought the 1610 version about 2 years ago and paid more than that. Purchased for making circuit boards, I had a lot of issues to start with, but after fitting a third different motor, it suddenly got a lot quieter and worked brilliantly. On closer inspection, it turned out the two previous motors were not running 100% true. I observed when using a small cutter that rather than cutting central, it was cutting circles. A piece of MDF bolted to the bed and flashed off level has also helped a lot. Sticking the board with double sided tape works a lot better than clamping the edges too.

I considered getting a bigger one, as I seem to be making bigger and bigger circuit boards and I am really struggling to get some circuits onto the bed, to the extend I am having to make two boards and link them together. However, I had the bright idea this week of extending the Y axis and fitting a larger bed at 90 degrees to the original which fits through the back of the frame. The plan is to use the existing bed, but bolt some 18mm MDF to the top of it, replacing the 2020 extrusion that extends to the front with two lengths at 460mm, the linear rods replaced with 500mm and the leadscrew with 500mm. I've done the frame and linear rods, just waiting on the longer leadscrew and MDF.
