I have an old Handi-Quilter 16. One of the first they made so it must be 10 years old. I love it and it has just made the 8,000 miles from SoCal to Santiago Chile. Had a table built here and it takes the whole guest room 10ft+. I have 2" either side b4 it's cement wall time. (The table was made to come part when we have to move :)
I mostly do my own goodies. I allow others to come and do their own Q's if they want to The machine is so simple. It goes up and down for crying out loud. I don't think I could kill it if I tried. (OK the computer chips maybe) Don't have many brave takers on the 'Q your own' option as they are intimidated. :) But I don't enjoy trying to work to s/o else's specifications. Let the mistakes be theirs is my motto. Although I let them practice first on a sheet sandwich I made from Thrift store acquisitions.
There are hand quilters here for $40 too and they are OK for the unlearned who just want a product and the batting here is mostly poly. I have the only Q'ing machine for 1,000 mile so I will be getting more requests for custom work I imagine. OTOH not all that many patcher's BG.
