The BL Crown Jewel was on my list of potential purchases. If I remember correctly, it doesn't need to be oiled, which is a positive, but that might be because it doesn't stitch as quickly. However, I've never needed to stitch super fast anyway. I mean, how fast would you really want to go anyway?
The price on the BL is better than the HQ too (at least around here anyway) and the computer update on it is really nice and easy to figure out.
I did not like the bobbin winder. It was not attached to the machine. To me it looked like a middle school project. Otherwise, I did like that machine a lot. I chose a different machine, but my final decision was based on local dealer support more than anything else.
Good luck on your decision. Isn't it exciting?
