Hi Shadow,
I use Fisher Space pens at work but to have the problem of losing them, which does not make the boss happy.
So I was at a store called "Dollarama" and saw a silver metal pen (made in China) that looked like it would take a Fisher refill, it was only a buck so I bought it. Sure enough the refill worked great, but I lost the pen within a week of buying it. I went back to the store to buy 5 more but there was none left and I have not seen them stocked there since!

P.S. I found the one I lost in my old raincoat recently but when I went to get it to write this post, it is gone again!
