Hello, I have the Ilford 500 H head and I love it. Split filter printing is a breaze because I can program up to 9 different exposures for a print. Rarely do I use more tha 3 or 4 but the possibilities are great. The head is also very bright and when making small prints it is almost too fast. Plus the mixing boxes decrease exposuer times a lot. It is not built as well as some other heads but for personal use it is great. Good luck, Ken
