Busted Fazer - what are my options?

[Bias]

Long story short, 2 of the exhaust studs have snapped. A kind mechanic from York Suzuki rode to my place to take a look and says that because of the position of the studs (i.e behind the frame) it would be costly to fix as the engine will have to be removed

Sounds like an engine out to me or head off to me ....
