Welcome to Librarium Online!
Does any one know where can I find them(and don't say "Ebay" please)?
If your lucky enough to be in the vicinity of a GW or hobby store that hosts GW games (in particular WH40k ones) go along to a store on a game day and talk to some people and see if they have any old epic models lying around, you would be surprised what us collectors have stuck away in cupboards and basements you might be able to get a real bargain or two because haggling IRL is so much easier then online, if your lucky some people are like "hey give us $40 and come pick it up ill give you a whole box of epic stuff that is just lying in my basement" i was quite lucky because the first ever tournament i went to at my local GW i faced another nid player who wanted to sell his stuff cause he was switching to eldar, was able to grab a fex and three warriors for just $20 it was awesome. Mind you if you don't have access to a GW store or a Hobby Shop i am totally out of ideas for you, i know you didn't want it mentioned, but eBay is so very popular for a reason
anyways hope that helps

In all seriousness...eBay

Don't have GW and there aren't any Ebay sales that worth traking...=\
there is the DRM but they are "a bit" short on large creatures.
I have to jump on the band wagon and say eBay. You have to be patient with it. Check every day. Watch what things are selling for. Auctions will end with no bids all the time because the seller is asking too much. Usually it will get listed again within a few days with a lower price.
Also, on some buy it now items there's an option to make an offer. Someone was selling a used hierodule for 150 (4 dollars more then forgeworld. I sent him a message stating that. I offered him 110 and he took it.
I've been keeping my eyes open for an armorcast phantom titan since they released a new forgeworld one. I search for "warhammer Titan" every single day. I know for a fact that there's a crap ton on epic stuff just waiting to be snatched up.
