Bartertown.com FTW
Cryx Battlegroup I got from Bartertown.com
Look what I got in the mail today!
I have been recycling my gaming money for a long time now thanks to Bartertown.com. I think the only money I have been spending has been for shipping here and there. Also, anything I sell just goes into the "wargaming slush-funds" that if I do buy anything with, it is with that money. This has allowed me to switch armies and try new games (like Hordes and Warmachine). I really do suggest if you want to find good deals to check this site out. Heck, if you are just starting out and want to purchase something, you can typically find stuff for good prices. Lots of 50% off sales, etc. And if you wind up not liking it, you know you have a place that you can sell/trade for something else on. Paying just a little bit of shipping to try something out is always worth it in my mind.
I did that with AT-43 actually. Bought the starter box and played it for a couple months. While I was hoping the people I was playing it with would get into it and invest, no one did. So, I just reposted it and sold it only loosing like $7 on shipping. How many people would like to try out a game for that long for just $7? 
A few tips though:
- Try to make purchases from people who have good references. You can check a persons reference by 1) looking at their number by their username in a post and 2) look them up via Searching for their references
- If you are trading, the common etiquette seems to be lowest references ships first, but I have shipped at the same time with people who have higher or lower reputations than I do if they have pretty strong references
- When trading, one of the easiest ways to do determine if it is a good trade is compare retail costs of what you are trading. Now, with things that are out of print, this is harder to do, but try and think of what they would cost right now if they were brand new and then, if they are in demand, bump them up a bit in price. It just makes things easier and it is easier to justify to the person you are trading with
I have found by following these rules along with some common sense make trading on bartertown worth my while. Heck, I have actually met some cool people via private messages while trading and had some cool conversations.
So, if you are interested in getting rid of, trading, or buying wargaming gear (or for that matter other stuff, some people sell game consoles, guitars, dvds, etc looking for trades) give it a look-see.
