Pathway Readers. They are Amish or maybe Mennonite, but be careful with the later ones as there are suggestions of corporal punishment. But they are along the lines of Dick and Jane.
Open Court readers, out of print, but very enjoyable.

In the past you could print them up free from online.
Nora Gaydos readers are also phonics based, but I think more enjoyable than Bob books. It looks like they are now out of print, though, that’s a shame.
MCP phonics readers are similar and also a little more fun than Bob.
