Searching for a rip fence is maddening

Hey guys sorry to have to post this but I feel like I've exhausted all the options I can find or know of. I have a 27" Craftsman tablesaw (front to back) that I got from my grandpa and I want to get a fence for. I believe I should be looking for around 30" to account for the rails or runners but I can't find anything below $250. Surely there has to be some lower-grade options out there for $100-150? I'm fully comfortable making modifications to make something work that is not designed for my saw. If anyone has any leads let me know, this has been a frustrating search. Thank you!
