Basically looking for a good, smooth as butter, pen for everyday work/study stuff and because I write short stories entirely by hand - up to a value of around £120/$150.
I've been using a MB 14 (which is my favourite pen ever - very springy nib, and smooth as anything to write with) and a cheap Parker Frontier (which is very smooth too).
I prefer medium sized nibs and I'd prefer a piston filler (however cartridge is fine if I can get a converter).
I'd also prefer a nice vintage rather than a new one but not essential.
I hate heavier kind of pens as I write everything by hand, I have a Cross Beverly (I think) rollerball that I cannot use for extended periods of time. And a jinhao (I think it's called) that's far too heavy to use for very long.
So - hit me with your best suggestions.
