I'd like to try DMT before I die, but even while living in the Netherlands I'm having a hard time obtaining it. I might try extracting it myself some day but I'm not much of a DIY in that respect and I'd probably light up my garden shed.
You could try Ayahuasca. It should be a bit easier to prepare than pure DMT, and more pleasant to consume too. The plants needed to make it are legal; the result is not, but since you're going to consume it soon after, I wouldn't worry about it. Just make sure that you consume no tyramine some time before and afterwards.
I'm interested in trying it myself, 'self-transforming machine elves' sound very interesting.
The Doors of Perception is his best work. I always felt that there was something lacking in his fiction. Enjoyable, but I could never quite call it literature.
If you want to know more about DMT-related stuff then check out podcast Gnostic Media on iTunes and download episodes #35 and #58. Both of these are actually about 5-MeO-DMT, which is very different but equally interesting. Also there are a lot of really good Terence McKenna interviews on the Psychedelic Salon podcast, e.g. this Under The Teaching Tree series:
Of course there is also Rick Strassman's book The Spirit Molecule, as well as James Orock's book Tryptamine Palace which is about 5-Meo-DMT. I'm way too scared to try either, but really interesting stuff.
