You should honestly consider purchasing a fountain pen. They work via capillary action, which means that they write on contact -- no pressure needed. At all.

Some good starters are the LAMY Safari, the TWSBI 540, and the Kaweco Sport. All of these cost <$50 and can take bottled ink (with possible modifications to the Kaweco), reducing refill costs drastically.

I, too, used to think gel pens were the bomb, but writing with a fountain pen is just something else. :D
