Hello. I plan on buying an 18k VP (probably a Decimo) in the near future, and I am considering alternating between nib assemblies rather than whole pens because of high cost, since apparently it is easy to keep an inked nib assembly from drying out, ready to switch quickly, unlike with most nib switching in other pens. Anybody knows about good prices on VP nib assemblies? A not so recent review suggested they can be had for about $35, but I have not found anything for less than about $61, which is not far from a whole capless steel nib pen, and waiting patiently for some big discounts on a whole 18k pen seems persuasive considering current prices of the nib assembly. Any and all tips on better prices (lower than $61) much appreciated.
