Depends on the value of the kit and how many rolls you can process. I did this many years ago when I first started.....it was simple and fun, all you need to be very accurate about is the tempertature, if you keep your tank in a water bath at the temperature required you will be successful. The one I used was the Beseler 4 step...and then I think they came out with a 2 step. In any case, give it a shot, I think you will enjoy it.(posted 8317 days ago)
