The Ilford 500H light source, 500S power supply, and 500C (or CPM) controller are nice to use. I'd recommend getting a foot switch for it, too. Like all choices, these have their pluses and minuses, but overall, I think it is a good system. If you get it, and have any questions about its functioning or maintenance, I'd be happy to offer advice (from Ireland), and I'm sure you'll find other users of it here, too.
