I am a recent fan of the Sensa line of pens and found out that it is being discontinued, so you can get really great deals right now. I picked up 2 from Altman Luggage for $15 and $18 each and another 3 from ebay. If you decide to buy, watch the descriptions. Some are ball point and take only ball point refills, others are "gel" and take ballpoint, gel, or rollerball refills, all three. The latter is far superior. Be warned though that the Parker refills are not cheap ($5/each). i'm sure there are less expensive alternatives but I haven't had time to research it.

Also, I've had luck with a seller on ebay whose handle is "pensnmore".(no affiliation, etc) I bought a trio from them for $24.95 (ballpoints) and I'm ordering another trio of gels to tuck away as gifts for folks in my office. They have a phone number somewhere in the listings - for the second set I called directly so I could specify colors and styles I wanted.

Anyway, thought someone out there might be interested.
