I simply CANNOT thank you girls enough!!! Because of your answers, and my non-existent knowledge on this subject, I have decided to let this deal pass. It makes really good sense to me when you spoke of the 9" throat. I really do not want to need to upgrade at any point. I don't mind upgrading because I WANT to, but I don't want to have to. I hope this makes sense, Thank you so much for being my conscience and keeping me straight. With much Gratitude, Wendy
