I have a Cut-3000 (AKA GCC Bengal) and it works just fine...Much quieter than a stepper motor driven plotter....But I think it would be better to compare a GCC Puma III to a Graphtec CE-5000-60...
Not sure if you need contour cut, but the Bengal does not have it...A Puma III is about 1400.00 with stand and a Bengal is about 900.00 with no stand...Also, I get the feeling that the Bengal is being phased out in favour of the GCC Expert Pro...
Another option is a Zencut Black which is also GCC based but does not come with Great Cut software...That would be the deal breaker for me...
I have not heard the expert pro is replacing the Bengal and I doubt if it will,, the Expert pro is just a Puma II, it is basically the Puma III without a optical eye,, comes with a stand and has only a one year warranty.
The Puma III as it stands now with a stand is $1340.00, this is because they replaced the Puma stand with a universal stand that fits several models and is a lot less money than the original Puma stand.
The Zencut is a spec GCC,, in other words they had them built and had them built with less expensive parts in areas so they could get the price down,, at least with GCC you always have factory supplied service and parts available.
Spec wise the Puma III has better specs then the Graphtec,, They are both great machines.... If I were to purchase my last machine it would be the Jaguar IV,, just blows them all away.
