I've used a Lee trimmer in the past and was satisfied until I recently found a different case trimmer. It's called WFT (worlds finest trimmer) and can be ordered through Sinclair. It fits into a drill and after adjustments one can easily trim 15 to 20 cases a minute. The down side is it's caliber specific and costs $65. Not to bash Lee or steal your thread but if one is looking for a trimmer consider the WFT.
