so no to the videomic then? there are plenty of 1/8" to 1/4" adapters out there. i think most 1/4" mics are dynamic, and usually not shotguns. i'm not sure what you're recording with, but dynamic mics don't work well with a lot of the portable recorders people are using now.
but if you're not looking for something like the videomic, you should probably check out what tom said and get an xlr to 1/4" adapter. just a guess, but you may run into problems with phantom powered mics doing that. you'd have to ask someone more knowledgeable in that area than me
You can always go with an ATR-55 by Audio Technica. They are about 70-80 bucks new, and they have a 1/8" jack. It's far from professional, but if you are set on getting a non-XLR mic, you probably aren't looking for anything professional.
