I pulled the trigger a while back and got them and immediately fell in love!! They are great for many, many things. Mine get used a lot. One place it saves a huge amount of time is with pickled garlic. That can take months to develop flavor but under pressure it's a week and a half to two weeks. Folks have covered the rest of your questions.
Not a thing wrong with using regular cukes. Just put the alum powder in per the directions and you'll get really good pickles and they stay nice and crispy. I prefer pickling cukes but have done many jars with regular cukes and nobody can tell the difference but me, and even that's marginal. The alum powder is what makes the difference. I believe Steve uses something called pickle crisp or something to that effect.

[/QUOTE yeah read about pickle crisp. What happens if you don't use any crisping agent? I have only pickled habaneros and did not feel I would need the crisping agent on those....but a pickle, might be different.
