I'll have to look into it with Avid and see if it would be an easy upgrade or not. But if not I definitely don't want to have to sell the 4x4 one day and waste all that money. I'm looking to build a really nice shop and not be cheap, but I'm super cheap at my core..
If you are going the AVID route, you actually do have the option of expansion later to 8' or even 10' if you want to do a vertical milling solution at the front end. (Check out Jay Bates' AVID setup on YouTube) If I were opting for an AVID machine, I'd put more money upfront into the gantry/spindle and consider a more industrial controller like Acorn as an alternative to Mach4 and add the longer bed later since that's actually an option to add-on. WIth my heavier Camaster, you need to buy the size you want/need since expansion isn't going to happen with an industrial type design.
