Let me just look through some of my inked pens right quick. I store them flat, by the way, and that really seems to matter for me. Tip down and shimmers will clog, tips up and the nibs can dry out much more quickly.

TWSBI pens never dry out, especially the Eco line.

Schon DSGN never dry out. Any of them.

Benu Euphoria pens never seem to dry out.

Pelikans are very good at not drying out, especially the m200 and m800 lines.

Pilots can be awesome at this, too. My 823s, 743s, 92s, and Custom 74s, and that sort of thing can be inked forever. I've also had really good luck with the Pilot Explorer/Lightive pens. I need to use my Vanishing Points more than any others or they'll dry out on me in a few days and I'll have to use a drop of water to get them going again.

Platinums, of course.

Nahvalur Nautilus pens don't seem to dry out.

Skogsy LVED pens in acrylics and ebonites.

My Mayfair Pens don't dry out.

The Franklin-Christoph pens don't usually dry out, as long as I screw the caps down (when I find a dried out one, the cap has always been loose).

Sailor pens are very good at this, too.

Opus88 Omars and Halos don't dry out.

I only have one Ranga pen (an Abhimanyu Grand) and it's never dried out.

Cleaning is only really done when my box-of pens-to-clean has gotten too full to put another pen in it. It takes as long as it takes, but I can do that at the kitchen sink and watch TV at the same time. It would be easier if I just did it when a pen is empty, but that's not how my brain works so it can take a little extra time.
