At one stage I lusted after the K & M one with the indicator, and to a lesser extent the Sinclair. In the end I couldn't see the point of the expence of either. I already use an RCBS (with the universal jaw) which gives me speed, no handling of primers and above all else feel. The Sinclair and K & M don't have speed but will have feel with the minus of having to handle the primers. I also have an old Lyman 310 Handtool which I can use which is a single primer at a time type which gives good feel. So yeh, great tools but my RCBS does as good a job. I don't need a dial indicator for depth indication, I can do that by sensing pressure on the handle to seat the primer and I then always run my fore-finger over the seated primer and I can tell if it is properly seated. Interestingly each of the cartridges I load has a slightly different feel when seating the primers despite the brass mostly being the same brand. I have never used a press for priming.
