Advice on acquiring a Lunar & Martian meteorite

I would like to acquire both types of meteorites. Not slices or sections but whole meteorites. I'd like to avoid the "eyepiece aquisition disease". You know, starting off with $25 Russian Plossls and going thru the spectrum, finally settling with Naglers and Pentax XW's. The idea being to get a really nice meteorite and not want to trade or sell up. How does one become educated and acquire that nice Lunar & Martian meteorite? Are there individuals that can be relied on to deal with novices? Thanks for your advice and guidance.
