The manufacturers of some of the components have raised their prices. We were shocked to find ourselves selling the PPP at below our cost! So, we really, really regret that we gotta follow suit and raise our price by $15... to $50 per PPP.
Dj. (with some help from me, Daddy Elaine) is looking into the possibility of going into manufacture for himself, just to keep costs down, so watch this space... I forsee a great deal more experimentation in our futures.
