Keep in mind that the TinLizzie machines are the same as the Pfaff/Viking machines. The HQ are the same as the BL machines. If you find you really like HQ for instance, you may be able to get essentially the same machine for a better price under the BL name (although HQ has a frame with the additional take up bar (dead bar) which I wish I had on my machine).
Michael from SewNPlace is there with the new Juki. I suspect that machine will be great and he'll probably be offering a great deal since it was just recently released. It has the extra take up bar and an extra high harp. It also has automatic scissors.
I saw Innova, APQS, Gammill, Juki and Tin Lizzie.
Good luck looking around. Remember, if you can't decide yet, the Hershey show is only a few months away!
