I have the GX-24 and PNC 1000A ( earlier version of the pnc1100 )
The PNC 1000A in 15 years, never needed a part, always runs and
simple to operate. I use it almost every day. Limitations are 20 inch width.
I have designed HUGE complicated files in Corel, exported them in .eps files
to SignMate, never had a problem and can cut any length.
If I had a PNC 1100 ( 24 inch width ) or could have found one when I needed it
I would have never bought the GX 24. By the time I have to tell the GX24
what to do, the old PNC 1000A is half way through the job.
I only use the GX24 when I need more than a 20 inch wide cut. And maybe
one day I might have use for the electronic eye of the GX24,... maybe.
PNC 1000's and 1100's have been advertised for 300-400 dollars.
For a newbie, I think it is a excellent starter machine. Very little programming
and no electronic eye to deal with. Before buying one of these old machines,
see it operate first. Later, if you wish, buy a newer machine and keep the old
one for a backup. One good thing about newer machines is warranty and tec support.
But you are also spending about 1200.00 plus more for it too.
Good Luck
