Two Hot Vintage MTB Commuter Setups - The Radavist

I WANT something like this, and there is nothing local on craigslist.. I can ebay a frame for 1-200 USD…but I have no idea how much vintage old parts will end up costing. I feel like this bike will be better to tow my kids around on, put skinny tires on for some road use, and not cost as much as a cyclocross bike while still being able to do the same thing….and last generations.

any more modern wheel sets that are cheap and easy to obtain that would work? anybody recommend a certain cheap cromo frame?
