I make leather totes and handbags.  I have also made a few pair of outsewn shoes.   
I want to buy a machine mainly for the handbags.  I currently use my home machine and it does okay with upholstery weight seams but cannot handle too many layers. 
Juki? Chandler?  Cowboy?  Techsew? 
I wish I knew what I needed so I could just buy it.  I know I need a walking foot but do not know I need a flatbed or a post bed. 
Any help would be appreciated.
