Post all your minecraft 1.2.3 seeds here. it can be anything as long as it is cool. I have one. Make it superflat and type in "gimmeabreak" with no quotations. The chests have all sorts of awesome stuff in it.
to Toco150: Even though it is on superflat, it will always spawn the same. The seed spawns you right next to a village, and in some of the houses, there are chests. in those chests, there are many rewards, including diamonds.
Thank you guys all! I know i am not very popular, but i hope to get more and more popular. Right now, i am working on a custom map. It will be done pretty soon! thank you all for posting! Here is a notch and some diamonds!
I found a nice mountain starting zone with a forest, beach, snow and swamp all nearby. I did not locate a town super close, but there are plenty of caves to explore. There are tons of cliffs and good sized mountains. Small islands around too. My favorite is the crater in the middle of the mountains directly in front of the spawn.
