A good alternative to tray development you may want to look into is using the "Taco Method" as visually explained here: http://www.flickr.com/photos/digi-fi...7627864733730/

I use this all the time and have experienced no scratching issues on the film. The key is you have to buy hair bands with no clasp, hard plastic or metal on them that could scratch the film. That will allow you to develop up to four sheets of film at a time in a single Patterson Universal Tank. I use about 700ml of Xtol (one shot developer) to fill the tank. Works great with stand development with Rodinal at 1:100 as well. There are all sorts of options for home developing these days but that's the one I use.
