I have the older model Tin Lizzie and I use all brands of thread. I know many Lizzie users use King Tut thread, I think it is the recomended brand and many people say they have trouble with the cheaper brands.
I have never felt comfortable spending alot for thread so I use whatever is available at a reasonable price on the net. I've used coats & clark, YLI, and am currently using Thread Art (very cheap). I do have to brush out the lint often, the cheap thread is more linty. All the thread I use is cotton.
My machine is and always has been fairly loud. I think this is normal for my machine. I oil and clean before each use. If you think something is wrong with your machine you should call the Tin Lizzie company, they are helpful. You might look at the Tin Lizzie Yahoo group for a lot of support and answers. There are many people who know more than I do, and they are glad to help.
Enjoy your machine, take your time learning. Mary
