I guess it just depends on the sample lot !
Some one may buy 5 pens and get all good ones and say they have 100% success ..
Another buys 5 and gets all faulty pens 100% garbage ..
Then some one may have 50 or more pens and find that quality is very hit or miss ..
I love talk about QC , but what is required is a decent sample lot before any meaningful data can be extracted .
Personally I don't know how many Chinese FP's I own currently , certainly its North of 50 , I don't know how North , I hope I am not North of 100 ...
Anyhow , from say $1 to $15 for some pens ( I have a few Euro Budget FP's now ) ...
I don't know that quality varies that greatly ..
Would be nice if it did .
So far I have tested about 30 pens and only a very small number would I call keeper ...
I would love to see more FP meet and greets ...
A venue to which to take your pens and compare them to other pens ..
Because - How do you know if you have a good pen or not ? or even - What is a good pen ? Till you have actually used one !
The guy that has used a thousand fountain pens just might have some idea of what is good .
Does more money buy good ? And how do you know ?
We all have our own level or expectation of good , but where is the universal reference point ?
We all know NQR or broken , but good ?
If you have only eaten bad food all your life , how do you conceptualize good food ?
Or if you have only driven bad cars all your life , how can you comprehend good ?
Did I wander off track there , sorry ....
Not everyone is going to rush out and buy a $1000 fountain pen , so where does good start ?
I would love to try a good pen , that way I could really say where a budget pen falls on the yardstick .
To date I have not tried anything superior to a decent BP pen ...
