Before I got my 30 element Beam at a swap meet, I was using a homemade 17 turn Helix. It was easy to make, and worked quite well. I would not say that the beam was any better, especially since the helix is circularly polarized. I still have it, and may swap it back into service some day.

One of these cheap, perhaps-not-perfect-but-good-enough VNAs would help tune it up:

(I have the v1, which is good up to ~900 MHz, and have been pleased with it.)
