Well, I have the 'official' Times Microwave kit that will do LMR-400, LMR-600 and comes with the strippers, chamfering tool, and crimpers. Not cheap, but I wasn't paying the bill.
For home use, I have a set very similar to this. It's worked just fine for RG-58, but never tried it with LMR-400. The strippers are pretty much useless, the crimpers do just fine. There are other similar sets out there. I suspect they are all made by the same overseas company.
