I absolutely love the feel of a gel pen, and tried out the Pentel Energel Liquid Gel Pen (picked it up at Walmart on a lark). Its phenomenal. I still get the gel feel while writing in my Moleskin, but the ink dries in under a second (I've tested this!). Very satisfied (its the only pen I purchase now).
I'm using the 0.7mm point, but intend to try the 0.5mm point in short order, as most of my writing is diagramming infrastructure/code/etc.
