I've used a Forster for years, but have recently begun using a Wilson/Sinclair with the Micrometer adjustment, and I like it a lot. The down side is you have to buy shellholders for each type of case you reload (308 based cases, 30-06 based cases, etc) since the case actually slips into the holder like it's a partial chamber. The new Redding also has a micrometer adjustment and might be worth looking into.
I always got frustrated trying to set up a trimmer for the correct length, but with the micrometer you can just dial it in.
