Ray I bought a Forester and have never regretted doing so and having tried others the fault found in them was in the quality of the cutters of being by far of less quality. I have owned my Forester since the 70's and I have yet to change the original cutter that came with it. But also keep in that it might have since changed as it seems as the years go by the quality of all things now being made also tends to be of inferior quality compared to what was made in the past.

Lee makes a great trimmer you can run in an electric drill if you can get it in the right size.

The Forester is a fine trimmer, if you get one also buy the drill adaptor for it makes trimming very painless and fast. Plus it works great for neck turning.

I have 2 Forsters and find nothing wrong with them. I also picked up a Wilson a couple of years back at a gun show. They are expensive new but can usually be found for cheap at the shows. Again its an excellent trimmer but the bushings for it can be a bit expensive.

Forster will sharpen your cutter for something like $9 plus shipping.

Forster.  Every time I do a batch I think about buying a motorized one, but it must not hurt enough because I never do. My "trimming"  is very often a second operation to radically shortening a case.  The first cut I do on my lathe.  The trimmer still has to take .010 - 020 off, so I work hard.  The cutter is still fine after several thousand cases in fifteen years.  Custom pilots are easy to make. 

I like my Lyman because it cuts well, but also has the universal shell holder, so I don't need to change shell holders when I change brass. It's also quick release so a 1/4 turn on the handle releases the shell to remove it.
I'm too cheap to buy the power unit, so I removed the crank handle and made up a shaft to thread into it's place. I put my battery drive drill motor on it, and it works great to power it.
