I, too, would wait to see the specs on the new Expression. If there is a new edition coming out, the price for the original Expression with go way down. If you can wait and decide that the E2 doesn't do that much 'more' or not enough to warrant your purchasing it, the original E will be at the lowered price.
But who am I to give advice, bought the Create because I make mostly cards but got the into making favor boxes and 'had' to have the Expression because the Create could not make large enough containers.
Enjoy both machines - take the Create to classes because my friend takes her Expression and let's me use it if the image is too big for my Create.
There are always sales for machines at really good prices. I, for one, don't like to buy a 'package deal' because I want to chose the accessories I know I will use - cartridges, embossing folders, tool kits, etc.
Hope you enjoy using your machine - whichever you choose!
