visit the handiquilter web site-
it of course depends on the age and condition of the set up= there have been some great upgrades in the past couple years- new wheels- new track system- new lighting---
visit the site- look at how they look-what they feature- what comes with them===then you will know what you are looking at-
make sure the lights are working- does it have the laser stylis? does it have the stitch regulator?
good luck- i love my hq-16- for 8 years now!
