Travis way back in the day I had the pump handle Tippmann Boss which is a stitcher, not a sewing machine. I started out with my Artisan 797ABLTHR flat bed because I could do the heavier stuff on the Tippmann. I worked that combination successfully for about a year and then I got my Artisan $4000. My thinking was that I could do the heavy stitching either on the Tippmann or by hand, but the finer stitching for inlays and lighter weight item such as chaps and chinks, spur leathers and other cowboy gear. Even today the little 797 gets used three or four times on each sheath and the 4000 for the final edge stitching only.
So if I could only have one machine right now, I'd still go with the motorized flat bed but I'd be very sure it could handle up to 3/8" thickness if it had to, and based on my absolute satisfaction with Artisan it would probably be the 2nd or 3rd generation 1797AB.

Edited to add: The Artisan 3000 wasn't born yet when I got my 4000. If I was buying today it would be the 3000 for sure and I'd put the rest of my $4000 that I paid back then in my pocket. Great machines, much lower prices, now.
