Hello again! I'm on the lookout for a new grain focuser. I have a plastic Paterson job, and it doesn't do a good job. It's pretty dim (being made of plastic) and doesn't really help focus anything. It's REALLY hard to tell when it's focused. Can anyone recommend a good focuser, one that will last? The ones we have in our lab at school are all-one piece of metal, and they seem to do the job well. Does anyone have experience with this one: http://www.freestylephoto.biz/4731099-Deluxe-Grain-Focuser?cat_id=1602 ? Is it any good? I don't want to spend a lot of money.
