I've been using various iterations of Lee hand held priming tools for 20+ years with good results, but not without some problems. The ErgoPrime is my current choice, but the plastic tray covers are a weak link and I occasionally get misfeeds and inadequately seated primers. Lee has very good customer service, so any broken parts have been replaced. I've also tried priming devices from Hornady and RCBS and just couldn't warm up to them.
I decided to look at everything available and bought a K&M Priming Tool from Midway (had my birthday discount as well). This requires putting each primer in the tool manually, so it's a bit slower. The tool is all steel, no plastic or pot metal, so it feels like it will last a lifetime. Leverage is excellent. It uses the Lee priming tool shell holders, of which I already have a complete set. I've now primed over 500 .38 Special and .45 ACP cases with this tool and am delighted. The seating depth is very finely adjustable and very reproducible. I use a Pacific primer turning plate that I bought about 45 years ago to get the primers turned upright and on a flat surface. I highly recommend this tool if you like hand-held priming.
