John, just be sure your digital darkroom does not compromise your LF chromes! For example, using a scanner with a low Dmax, and Drange can reduce the beauty of the chrome by compromising highlights and shadows. I would say, the printing aspect is much more cost effective these days.... a printer under $1,000 now can produce prints as nice as a darkroom... however a, $1,000 scanner will produce very inferior results compared to an expensive drum scanner. So be sure you are working in the range you are comfortable wiht... be sure you know your max. enlargment you will make before outsourcing, then test some out before you buy... If you are not going to have very large files and plan not to use photoshop extensivly, I think the used Mac is a good idea...
