All the repro bayonets I've seen were in the $75 range, and you're not going much higher than that for a real one. I'd check ebayonet.com & see what his prices are. Ebay prices tend to push the envelope, as your market is in the millions... If you have any gun or militaria shows nearby I'd check them before I bought as well. You could ask on the bayonet forum what the most common makers & years are, to get a better idea of what reasonable prices are. I bought a 98/05 3 yrs ago at a show for $90(and a s98 in the mid eighties for $15). Watch out, bayonet collecting can be as addictive as rifle collecting (I'm two German 1871 bayonets short of having all my rifles properly attired, with only a dozen extra bayonets!).
