Thanks for everyone's input.
I've been a little hesitant about purchasing a completely computerized machine, but I've loved it when I've used it in the store.
I'm sure there will be a learning curve, but I really need a machine with a bigger bed...and WANT more features than I have now. The 875 has features I didn't even know existed. I guess I've been quilting in a cave with my old Singer. =)
Thanks again for your help!
I'll let you know what I decide..and post pics when I bring the new girl home. =)
