Fountain pen technology has come a long way! I've never had any problems with leaky pens. You can get some very nice fountain pens for around $20 these days.
They go for around $2 each.
If you want to feel fancier, the Pilot Metropolitan uses the same nib (in fact, since they don't sell replacements, you end up buying a pack of Varsities if you need to replace the nib).
