I would avoid any trimmers with the collet style case holder. In my opinion they are slow and apt to misalign the case. I had one and replace it with a RCBS Case Trim Pro 2, and what a difference, night an day. The RCBS works great and utilizes their univeral case holder with a clamping mechanism to hold the case against a reference point. It is much quicker to take cases in and out than the collet style.
I just used my RCBS trimmer last night and did 125, 30-06 and about 50, 300 AAC Blackout. I trimmed, and inside and out chamfered (by hand), and primered all the 30-06 all of these in 2 hours. If if had a case prep center to chamfer it would have cut the time down significantly.
The other trimmer I would look into if you want to spend a little bit more money is a L.E. Wilson, they use specialty case gauges to hold the cases, and they reference off of the shoulders of the cases, so you buy a case gauge for a family of cases that have the same shoulder. I've never used one but thought long and hard about saving for one rather than the RCBS.
The individual Lee Trimmers that people have been posting about are great as well.
But please save yourself some headache and avoid the collet style trimmers.
