You could also go vintage!
Don't worry about reliablility as those old pens were built to last. One of my everyday writers is 83 years old!
There are many sellers on line that are trustworthy and sell nice affordable pens.
Here is one who comes to mind who services the pens before sale.
I found a lovely of burgundy English Parker with box, fine/medium 14k nib for $100 (7th Down)

Those old parkers are lovely writers and this has the bullet proof aeromatic filling system!
Then with the same seller a whole bunch of excellent Sheaffers (I am sure Richard will attest to the writing experience those give) at well under $100, you would have a great pen and enough left over for a couple of bottles of ink!

There really is something writing with a vintage pen!
