If you like the Mars, then get one or a bunch of Uni Mitsubishi 2mm Mechanical pencils. I have been using them almost exclusively, when I use pencils, for over a year. They have a clutch system so you just advance the lead. I had no issue with the Mars and one is still in my desk but I just keep going for the Uni. No sharpener in the cap but those just get messy. Buy a Staedtler rotary action lead pointer and you are good to go.
I went to the link and I have to agree that is a nice looking pencil.
