The midwest seems to be an oasis for Krags.
Condition is very important when valueing Krags. Very fine 1898 rifles will bring near $1000 while good condition ones with shootable bores would be $500 guns. This assumes an all-complete rifle with cartouche, non-bubba'ed, etc.
Cut-downs and sporters are a $200 item, or valued like any other sporterized milsurp as shooters or hunting rifles.
At recent gun shows there have been several complete Krags priced around $600-750 on dealer tables that are not selling. I have not examined them closely as I have been Mosin hunting.
Seriously, I would be happy to hook you up with these dealers and do some advanced scouting for you. Just send me a PM
