you could have a look at PMC iB1S actives.
they are within that price range and are excellent speakers, active power is provided by bryston.
i wasnt that impressed when i listened to the air25's and found them somewhat gimmicky too but hey YMMV, monitors are a pretty personal thing and theres so many variables. maybe i just need to move forward with the times
you could also scour the second hand markets for some other options to maximise your cash so to speak. thats what i did when i got new floor standers in here. really made the money go further.
theres a lot out there if you dont mind working to find them.
