8173282897673080432 is a minecraft seed that spawns you on an island next to a village. I have not found very many seeds like this, usually the islands are fairly barren. There is a blacksmiths chest in the village with 3 diamonds in it!
There are not any trees on this island, but within a swimable distance you will be able to find some on other islands. There are plenty of pigs as well as a ravine near one of the ends of the island.
The 1.2.5 minecraft seed Old Spice is great. To begin with you spawn near an NPC village that is almost entirely submerged in water. Its coordinates are X: 288 Z: 186. There is a blacksmiths building in the village and it has 3 diamonds in the chest, Bonus!
Nearby the village at X: 196 Z: 121 is a huge pit, and it leads to a cave system that is great for exploring. I only explored for a couple of minutes in the cave and I found some diamonds at X: 200 Y: 11 Z: 13. I am sure there is plenty of other good finds in there for the intrepid spelunker.
A distance away at X: 13 Z: -382 is a second village in a desert biome. There is another blacksmiths chest, but its contents are less exciting than the first.
In the same desert is a 3rd village at X: 119 Z: -675 …thats a lot of villages in pretty close proximity.
