I hate cheap pens that have bad writing characteristics with a passion. If they skip, leave smears, feel flimsy and light in my hand, etc. I just won’t use them. So, I have settled on the Pilot G-2 (about $1 each) as my pen of choice. But thanks to a neat set of instructions somebody posted online I can try out what it would be like to have a really nice pen.
This Instructable points out that a certain Montblanc refill can be had for about $6 and with a minor modification it will fit into a G-2 shell, letting you try out the same ink used in multi-hundred dollar pens.
