For example,
Would something like these even be plausible? http://sandiego.craigslist.org/csd/art/2650973632.html
You could do both of those jobs on this one. And I could see how it would be handy for just names.
There is a shop here that does everything with a brother and only up to it's size restrances.
But with that said
I have seen Tajima, Barudan, SWF, Toyota and Melco for a thousand or 2.
My 3 Barudan's have Tajima heads and I think the new ones still do.
Age really does not matter on these as long as the up keep was good.
If it was me I would go for the Tajima, Barudan, or SWF's.
Look for a deal where you get the computer and punching software.
You will have to have the cables or a disk drive to talk to the emb machine.
Also the older disk drives use 3.5 720k DSDD disk and are getting hard to find.
If you could find one converted to a USB drive would be idea.
Also get one with a monitor...it's so much easier with one.
The old Barudan's use a 9 pin VGA monitor which is also hard to find.
The board alone to change to a newer monitor is a few grand.
I know that is a lot to think about, but might help you find the one you want in the used mkt.
