Hi, your goal of opening a saddle shop is admirable. I have never regretted doing the same. I think the hardest thing for me was trying to figure out what to charge for my services. I purchased a Cobra dream machine probably 6 to 8 months ago and am loving it, I have not found anything I can't do on it, and have not had any trouble with it short of it getting out of time which was caused by a saddle I was relining and the leather was quite brittle and I ended up breaking 6 needles before it was all said and done, after that it started skipping stitches so I timed it but it didn't seem to help so I called Steve and he helped me to get it right, I just didn't quite have it timed right, Steve is very knowledgeable and eager to help, I would definately recommend the class 4 cobra! Good luck with your business, Alan
