the cheap/low-end Sheaffer fountain pen line & the future

[robertb-sheaffer@xxxxxxxxx (Robert)]

About 6 years ago, I bought a number of cheap/low-end Sheaffer fountain pens.
At first, I liked the writing (I have a hand injury), but later I liked the
ink color selection.  I discovered yesterday that these pens are no longer
being manufactured.  This bummed me out greatly.

I'm trying decide what to do since I've grown so dependent upon these pens.
Yesterday and today, I've been buying all the colored (I use green, red, and
blue) ink cartridges on the assumption that these will be the first to go
(at least, before the black ink).

Some questions:

1) Are any pens from the old Sheaffer fountain pen line still available for
   a reasonable price?

2) How much longer will Sheaffer colored ink cartridges be available?

3) Are there any fountain pen alternatives to Sheaffer that also provide
   multiple colored ink for a reasonable price (when I finally run out)?
   For example, does Parker provide multiple colored ink?
