I have the Queen Quilter Tin Lizzie 18 i'v had it now for about 3 or 4 yrs now. I did not have any major issues with tension or anything. If I did have issues, it was always always operator error, so not sure from previous posting why there was negative responses to this machine...Anyhow, it comes down to each personal preferences. Each machine will have positives and negatives...Test drive if you can. I didn't have any places to go and test drive any longarm machines. My Fiance just decided to purchase one for a Christmas gift one year and well here now I have a longarm.
