I have a Blaze XT from Crosman that i got for 74 bucks at wally world that is just a overall wonderful rifle.
.25 cal Hatsan Edge with a peep sight.
It might not be considered a "budget" rifle by some people's standards, but I bought one of the last Benjamin Summit rifles (.22, NP2) on sale new for $170 OTD before they stopped making that particular model. I wanted this particular model because it had a little more of a traditional look to it rather than it's NP2 Trail sibling. I also find it more accurate and so far much more reliable than the Crosman F4 .177 that I bought last year from Wally-world.
