Looking For Commercial Embroidery Machine

I am looking for a used commercial (or semi-commercial) embroidery machine. I currently have a home machine I use to do embroidery and am outgrowing the capabilities of the machine. I would prefer a single-head machine with atleast six needles. I am looking to spend around $2,000 to $3,000. I am in the Atlanta, GA area. Please email me at oogieoriginals@hotmail.com if you have anything that might fit my needs. Thanks!
