Alex, the Linhof Super Rollex and Horseman roll holders are both fine products. The difference is that the Super Rollex is "overengineered" and built to last a lifetime. As a consequence, it's much heavier and, when purchased new, much more expensive. It's also possible that it maintains film plane register with slightly greater precision. But most users (myself included) find that the Horseman works well too, so it's really a personal choice as to whether the superior construction of the Linhof is worth the extra money and weight.Originally Posted by Alexz
Other modern roll holders more or less readily available include Sinar, Calumet, Wista and Toyo. Most recently some Chinese vendors have also entered the market with 6x12 and 6x17 "multiformat" holders of fairly primitive design but reasonably solid construction.
