I just use a typical 12v wallwart - puts out a pretty consistant 14.4v - which is perfect for driving arrays of 4 (3.6v to each), add in a 700ohm resistor - and you've got 20ma @ 3.6vdc.

Watch for his auctions that start at >10$ I got my first 20 LEDs for 7.99. The most recent purchase wasn't only 28$.

And the blues are much too blue for regular use - just the regular ultra bright white or whatever he calls them.
