My First Bailey was a 13 now I own Bailey 15, My first frame was a Little Gracie 11 .. Now I have my Bailey 15 on a SuzyQ king ..I haven't had any problems with Bailey but I've found that it loves cotton thread.. top and bobbin more than any other kind.. Also I have found there is difference between the 13 and 15 Bailey's .. On the 15 I can use pantographs up to 11" but It's a sure thing if one would go with a 10" pantograph.. The last quilting turn most of the time is lots less room to quilt in .. still no problem to make adjustments .. As for Throat space, I can roll an oversize King under the throat. no problem there either!
By the way, I have bought both of my machines sight unseen and I don't regret it at all.. These Bailey's don't have any bells or whistles but they're work horses!
