Hi I agree with Rhonda K. I have a niece with a multi needle machine and her let down was the amount of time it takes to set up ,she sells product and has gone back to using 2 single needle machines .Once the multi needle is set up it really fast, but most time she can get small jobs done faster in the single needle machine.I personally have thought of purchasing 15 needle but a lot of my projects have 40-50 colors and I would reprogramming color changes 4 times project and re threading as well ,I'll stick to a single needle .The service on these machines can be very expensive if you can't get it to a dealer close by, most call out fee's are around $175 these days plus what ever has to be repaired. A 10 needle machine would be very heavy, I wouldn't like to be lugging it around. Brands to look are Babylock- Brother- Lucky, all are proven good runners
