There seem to be quite a lot of alternatives:
Airbus A318 -
BAe 146- reputation precedes them, however as Cobham have proven, they do the job very well.
Boeing 717- too big 125 seats, too expensive, maybe ACN/PCN?
COMAC ARJ21- not at all familiar with this one, but too small, 2000 mts TORR sound a bit much unless they mean TODR in any case first of type and being a relatively new Chinese manufacturer, Not for me.
Bombardier Canadair Regional Jet- expensive and as Ansett/Kendals proved, don't do the job all that well.
Embraer E-Jets- ask Virgin about the E jet.
Fairchild Dornier 728 family- first of type with all the associated problems and 80 pax is probably too small.
Tupolev Tu-334- have o agree with WITW,
Yakovlev Yak-42D
