A question about pens.

I'm left-handed and I prefer writing with fountain pens. With ballpoints and the like I produce scratchy nonsense.

For years I've used disposable fountain pens - Pilot V or whatever Bic's pens are called.

I feel a little bit bad about the single-use plastic, but I like having pens in lots of places.

Pilot V-pens are getting more expensive, and I'm not sure if Bic even make theirs any more. I'd like to avoid Amazon if possible.

So, what should I buy? Is there anything non-Amazon for less than £2 per pen, or is there a cheap cartridge pen that I can buy half a dozen of without immediately regretting it?

EDIT: I've used Lamy in the past and I don't enjoy the grip.
