In addition the suppliers at the top of the page call Ferdco . They have a web site http://www.ferdco.com/ . They are super nice folks and will help you anyway they can, or they have always helped me anyway. I have had a Juki Pro 2000 for 10 or 12 years now and never have had a problem with it. I do leather work full time and make a little bit of everthing. It will sew your holsters no problem i've made a bunch of them.
Just like the others said get at least a 16 inch arm no matter what brand you buy, you will be glad you did. Because some where along the line you wil need the extra length and it's nice to have.
