I own more than 20 FPs (from Waterman , Pelikan to MBs , Delta, Aurora y Omas.
Now I am after the Namiki and ANCORA ones.
I also own some Rep FPs.
I can tell you that there is not a single good replica FP. Almost all of them are not good for writting.
Bad nibs , paper scratching , resistance , no continuous ink flow, bad pistons , .... etc , you name it.
Of course you can try to mod it (change Nib , piston etc..) but replacements are very hard to find.
So for FPs , my advise , stick to the real ones.
So , for rep brand names on pens stick to rollerballs.
BTW: This is by far the best place to buy a gen FP at excellent price. Also accepts Paypal.
