Save your money and just check your local Army surplus store when you get back. I went to the Maine Military Supply down in Brewer, Maine a few months ago, and they had plenty of both kinds (they also had an FN FAL bayonet at the time - too bad I didn't think to buy it 'cause I always wanted one) . A friend of mine ordered a couple of the AK spike bayonets last year from their website for $15 each before shipping, but they now only seem to have the bowie style one with the wire cutter built in. Great store to go to, if you're ever down there.
