What are some value for money fountain pens?

I am eyeing the more expensive fancy sailor pens in the range of 200 - 300 euros and read somewhere they are quite overpriced for what they are so I am wondering what are some good brands for fountain pens and inks.

Currently my collection consists of a clear 03 platinum preppy with a black ink cartridge. Once the cartridge is used up I am thinking of buying a herbin brown ink and the platinum converter. I do not want to get a big collection of FP as I always had a shopping problem but I want a good pen upgrade I will cherish as a treat after I finish some classes in 5 weeks and if I am still using my preppy fro writing.

So which are your favorite value for money FPs?
