I have a Forster trimmer, same one as Dan uses. Mine is so old, it was actually bought through Herters. Forster still makes parts for it.
Case trimming a lot of cases is a pain in the butt with most of the less expensive systems.
Lee's system is certainly cheap enough, and it works. The big drawback to the Lee set up is that it isn't adjustable- you can't decide what length to trim to, like you can with many others.
A number of trimmers now use a cordless screwdriver to power their systems, rather than by hand- much faster and easier. I suspect you could attach a power screwdriver to the Forster, but I haven't tried it. The reason I haven't tried the cordless screwdriver is because Forster has a neat power adapter for their trimmer. They sell a base that goes on a drill press. The base holds the collet that you put the case head in, and the base has a speed handle to make inserting and removing the case very easy. The trimmer pilot goes in the chuck of the drill press, and case length is set by the stop on the drill press. The system takes about 5 minutes to set up each time, but once you do, it's really fast. The only time I've ever timed how long it took to do some trimming with the drill press set up, I set up and did 300 cases in about 45-50 minutes. Of course, you must own a drill press, but, the advantage is, you'll never bog down a drill press trimming cases, which happens sometimes with the cordless screwdrivers.
