Celio generates all sorts of horror stories.  Many are virtually unplayable out of the box or become that way from things breaking in normal use.  There are stories of tone holes out of round and unlevel, solder joints failing, and springs flying off. 

If you want a good rock&roll horn for cheap, there are some good options in American horns from the 1950s and 60s.  The Conn 10Ms made from the late 1950s on are good rock&roll horns, as are the Conn Director (student model) horns from the late 50s through early 60s.  Later Directors went downhill in quality and durability.  Top dollar should be about a grand for a 10M (from that era) in top condition, a few hundred less for a Director in similar condition.  The Martin Indiana and Imperial are second line horns produced in the 50s and 60s that go for well under a grand.  One guy in the local R&B scene just replaced his Yamaha with an Imperial.  He's in love.
