I have 2- TP-Link WA855RE 300N wireless range extenders. $10 EACH or $15 for the pair.
They can be used as access points or repeaters (RETRANS for commo folks). They both work fine, I used them for a few years, but with three kids doing school from home and me working from home, I needed to upgrade to something faster. I have reset them to default. They are hardware V1.0.
