I've purchased it from CSI mail order for $18.
http://www.circuitspecialists.com/prod.itml/icOid/2825I got my last Kg from Fry's - it was about $14. 250 grams per liter
of water. It lasts for probably 15-20 moderate sized boards. I don't
know if it can be regenerated. I heat it to about 120 F via a hacked
aquarium heater and "dimmer" control. I really should build a temp
controller someday...
Because it's clear and doesn't stain, it is 10x better than FeCl. I
hate that stuff. Here's a picture of my tank with AP in it. The
stuff in the bottom disolves when I heat it.
