The 3800 is just a 3000 with a separate rip
Toss the rip.
The 3000 is still very much a good and workable machine. The problem is not inks (they are still available) or parts (used non-working 2000s and 3000s are available all over)... but that this printer is slow, and it needs to be run regularly because if the inks dry up or the printheads clog, you are gonna spend $225 (for a year & a half warranted) ink/printhead set. The good news, however, is that there are only 4 colors.
The other good news is that you can print 54" wide.
The other big problem is that time has been less than kind to these old gals! The displays are getting dim (I run a couple) and you had better be prepared to strip the machine all the way down at a moment's notice in order to replace a part from your spare machine (DO NOT BUY ONE OF THESE... DEFINITELY BUY 2).
I gotta admit, the next time my 3500 or 3000 asks for a cash infusion... even a printhead set.... I am gonna let em go. There are 5000s out there going for $500 in working condition.
