Glad you approve of the landscape, it seems to be what gets most people's attention. I'm not sure about it myself, but everyone seems to think I am especially good with landscaping. I was asked to write an article for C-C on it actually, unfortunately it's still only half-written. As for basic LEGO parts, I try to use them as much as possible. The entire MOC only has bricks, plates, 1x1 rounds, a couple technic pins for how it connects, 2x2x3 slopes, 2x2x1 inverted slopes, and flags and flagpoles. That's about all in the whole MOC. A few more slopes, probably.
I'm not sure how soon they'll run out - I'm pretty convinced they made more than 10,000 of each packet.
Indeed. Friends are good for LEGO, although one of mine partly knew the worth of his. But it was still an extremely good deal. For $100 Canadian I got this:

Several of the more worthwhile parts are shown here:

All in all, it had about 5,000 new pieces, many of which were rare and unique. Of course I carefully washed and checked each piece before I brought it into my collection.
