I have reading that there have been a number of pasta machine problems recently and even the machines breaking.  I have always used the Atlas pasta machine that my husband bought me when I first got into polymer clay a number of years ago.  It is a heavy duty machine, not very light to carry or move.  The only problem I have is that the handle falls off now and then but it does no damage.  I would be leery of a cheap machine that they now sell for claying.  They just look like they won’t hold up to the serious amount of use that a clayer may put them through.  They may hold up for the weekend crafter though. 

The only thing that I do with my Atlas is the run a heavy cloth over the blades to clean excess clay off of them.  I know that I can take the machine apart and do a deep cleaning but I have never seen the need.  One of these days I might, just to make sure that I can do it.
