Rating: 9/10
Price: ~$2.50

I am impressed with every pen I've used in Uni-ball's Sigo series. Apparently I have the older DX model, rather than the newer UM-151, but I believe I've used the UM-151 as well. 

I prefer the 0.38 size, as it fits my writing style well. The main difference between this pen and the Signo RT is that the DX is a stick pen, and the RT is retractable. This winner is available in several colors and in 0.28, 0.38, and 0.50 widths.
