B&H has nothing in stock except a 25 gallon bleach, unfortunately, so I might as well order online and have everything show up at my door.
I emailed PF yesterday to ask about the kits. If I recall correctly, they were quite expensive and not very high capacity, which is why I went with the Rollei. The Rollei was a good balance - a little pricey compared to buying the high-volume Kodak, but simple, good, and still much, much cheaper than a lab. And no blix!
Worst case scenario, I could buy four mini-Rolleis and get 40 rolls for $100. Not terrible, but I'd like to do better.
