Andy,
Welcome to the Krag forum.  Yes, this is the resource for Krags and other firearms too.  You are wise to seek advice before purchasing (unlike me). 

My first 1898 was obtained with the emotional enthusiasm of "I really want one".  Well, yeah, it bit me in the ass.  I can assure you that bore condition is most important.  My first rifle's bore looked like a century old sewer pipe and key-holed at 25 yds.  Plus it was plaqued with several other problems.  A new barrel later and it still anit right.  Ha!  I did a sight unseen via a competition shooters forum. 

My second rifle was just the opposite, a great shooter, original configuration, and a very good price.  It pays to shop around.
