I've been using my Puma III for a bit over a year now, and it has performed flawlessly for me. The optical eye has been handy to have for me when I use JPSS, or make some stickers that need to be cut out.
Something to consider with the Puma III vs the Expert, with the Puma III all of the settings for the cutter are there on the front panel of the machine. Whereas with the Expert series you have to use the VLCD software. I'm not knocking the VLCD software as I have never used it, just something to be aware of with the Expert.
Also when I purchased the Puma III, I also bought the Flatbed Table attachment, stand and an extra blade holder. I exclusively use CleanCut Blades in it as well, Roland Zecu 60 degree for StickyFlock and similar "thick" materials and Roland Zecu 45 degree for all my vinyls. IMHO
at least one extra blade holder is a must. So much easier to switch between cutting vinyl or flock.
And no matter what cutter you use, spend some time dialing in the blade depth and downforce settings. Keep notes of every change you make and you will be surprised as to how little downforce is really needed.
