Oh, shoot! That's the site that I recommended for FTA cards, as they charged
a reasonable price for kits that weren't all gussied up with unnecessary
features.
Blaine Bettinger recently had a blog entry about some alternatives (long URL,
ends in part-i )
http://www.thegeneticgenealogist.com/2007/08/28/dna-from-the-dead-dna-banking-is-legal-but-is-it-ethical-part-i/
One resource he didn't mention was DNA banking of a sample obtained from
whole blood. It might take something like that (or maybe even more) for futuristic
whole genome testing. Here's one resource for that method.

Blaine also mentioned the "Q-tip" method. I've heard lab technicians complain
that this method is hard to work with, as the DNA gets attached to multiple
cotton filaments.
FTA cards are still a good tradeoff of economy, efficiency, and ease of
storage. You can run several hundred tests on a DNA sample extracted from an FTA
card. However, several hundred may not be sufficient for all possible future
applications. I just read recently on the FTDNA forum that DNAPrint has found
that two swabs are insufficient for their Euro DNA 2.0 test (1,349 SNPs), and
we've heard about some FTDNA stored samples being insufficient for extensive
testing (e.g. multiple Y-SNP and mtDNA full sequences). If you go the FTA route,
I'd recommend saving several independent samples.
