depends if it is baltic or balkans, they are a way apart...
I would say you have a good deal, I recently bought insurance for Bosnia at Borsanska Gradski. It was a bit terrifying after leaving behind bike and passport and usured into a back street by a Serbian version of Derek Trotter. It was all OK but a weeks cover of 3rd party cover for Bosnia was 37 euros.
Whatever, you will find Bosnia a fanatstic tour. watch out for speed traps on the main routes, I think they are after easy toursit money. go far from the big roads if you can, they are fantasitc and much leas speed trap orientated.
Watch out when it rains, it often will wash large boulders into the road when you are in sharp sided passes. If you go to Sarajevo (you must) head for the hostel Posillipo. It is close to the old town, good place for bikes and Sabinia makes a lovely coffee, (Say Dave from UK sent you).
Have a great journey. It is a fantastic unspoilt place. the war is still raw in may places, it makes it a great trip, but don't go off roading if you can't guarentee mines haven't been cleared.
go easy Dude..
