I bought a used A-1 that I got for a great price. It was originally $17,500 so I feel pretty good about what I got it for. That said I bought it from a foreclosure and it was an as is. Someone else saw it ahead of me and passed because it had rained into the container it was stored in. The table was actually wet and the machine was not. I sent it to the factory, they gave it a spa treatment, I went to a weekend class with Jamie Wallen and all is well. I got a great set up for a great price and a little work.
My advise is to go out on that limb and buy the best set up you can. I would hate to have to switch to a new set up after this one is set up. I have stitch regulator and the hydraulics - I'm tall so I also have blocks under my feet on the table to make it higher to start.
I agree search for a used outfit and try everything you can.
