I only mention Pacer because thats probably the only name I've seen about. There was one local that was selling for 5.5k and had vaccum bed and was serviced 6 months ago. As the guy was local, any pointers I needed he would help. He was upgrading his machine and didn't have the space for the one he was selling.
Obviously the cheaper the better but I do understand what your saying about you get what you pay for.
Reason for getting one is that were wanting to expand, and we've probably passed about 15k to out sourcing this last 12 months, which the money we're saving on outsourcing would warrant buying one. But at the same time couldn't warrant spending 20k plus on one.
