One more little horn toot for LPD. You talk about economy.

As replenished, you use 300ml of replenisher per 30 8x10 prints. There's a gallon of replenisher with each kit, and 300ml fits about 13 times into a gallon. 13x30 = 390. That's how many prints you get out of a gallon kit of Ethol LPD. For a ten dollar can of powder. Not bad. That's in round number three pennies per print.

And it does last for at least six months. I always use it up before that, so I can't tell if it would last a year or not.
