I have the Horsman 6x7, 6x9 and 6x12 and the Sinar 6x9 and the Toyo 6x9. The Horseman is very fast to load and very easy to use and is much smaller as the Sinar and Toyo. So for outside it is the winner! In my studio I prefer the Sinar and Toyo because they slip under the groundglas for the Horseman you have to take the groundglas away!
You will be happy with the Horseman!
