I'd have bought that sucker if I had the coin.
Why? Right now the cheapest case on the Bay is going for around $1,400. Best case scenario, that gets me a Sheldon or Penny auto. I'd have to fork over another $900-$1000 or so for the rest of the top 5. So I'd have paid >$2,000 for a master set, and I'd be stuck with 10 bajillion base sets and Kripke autos.
Really, if you want master sets (and I do), the easiest and cheapest way is to just suck it up and buy the damn things.
