Want to buy SAE's

I've noticed that SAE's seem to be the algae eater of choice.  I am having a
hard time finding them in my area.  I would like any information on where I
can buy SAE's by mail order.  It seems that no one around here has them.
Otherwise, if anyone would like to sell any of their SAE's I would be
interested in that also.  Please e-mail me directly if you want to sell.
