Paul. Not sure of your building experience but will warn in the event that it's near the "feet wet" category--a DMM is a pretty demanding build. Madbean's docs are top notch(best in the business when it comes to complex builds imo) and help a lot, but it is still a big time undertaking. Not a lot of handholding to be had when it comes to troubleshooting builds like that. You'll also need at minimum a scope or a good DMM with accurate frequency counting.
I don't say this to deter you as I don't know your experience level. But if you're newish to the hobby/electronics, I would hesitate at least. I've just seen it a few times where a new builder takes on a big build, dumps a bunch of time and money in it, gets frustrated and disappears-- assumingly leaving the hobby. And I hate to see that.
