Sorry to read that your pasta maker is dying! I totally agree with Jackie. "Monafied" Atlas is a very good way to go. Pasting in info below I've posted previously.
"As far as new machine recommendations, many clayers (including me) recommend be the "Monafied" (modified) Atlas machines. It's a bit pricey, but well worth it in ease of use, ease of CLEANING, and high level of function for many years of use (if not abused by feeding in too thick chunks of clay, .....been there,done that). I own two of them.
The Monafied Atlas machines have METAL scrapers, rather than the plastic ones that now come with standard Atlas machines which don't work well with PC. The "Monafied Atlas has REMOVABLE scraper blades that can easily be removed for cleaning in less than a minute with the turn of a screw, unlike the regular Atlas machine that is challenging to take apart and clean. Mona sells both the #150= 150 mm (5.9 inches wide) and the #180= 180 mm (7.08 wide), with or without the motor. She is a clayer and her husband, Rainer, designed the modifications.
