I've used dan's machines for over three years now, but always for color and b&g, not lining.I recently got two of the sidewinders from dan, plus an mc14. I got the sidewinders for lining more than anything, but I must say I've never put color in as fast as I can with the sidewinders and a textured medium taper needle. literally one pass and the color is in 98%. it's just amazing. they aren't as quiet as dan's usual rotary machines(but not as noisy as a coil). I called dan and asked if he would take one back and let me buy a couple mc14's instead, after I realized they weren't the usual ultraquiet I'm used to with his machines. he agreed to do this. but then I used one of the sidewinders and it was all over. I love the quiet of his machines and I've become very spoiled by this low level of noise. I had to write and tell him thanks, but I was going to keep them both, after all. I felt like a nitwit. the savings in time packing color is amazing! and by the way, they are all amazing liners. very, very strong! no problem at all with 7's and 9's liners.
