I've got one of these and it's a nice enough machine, for what it is. As Wiz said, the needles are what I would call an odd-ball size. I fitted a roller foot but haven't actually used the machine much (it was free, but took a bit of work to get it running). It should sew what you want, but If you're looking for your first leather machine this is probably not the right one to get (I consider it more like a second machine when someone already has a suitable leather machine). A bit of advice, if you think you'll be getting into leatherwork then seriously consider a walking foot machine. It will be much more suitable for leatherwork and as Wiz also said factor in a servo motor. You'll be struggling with anything less than this combination.
