This seed i just found is a good island seed that starts you right next to a ravine (x1801,y68,z583) but even more wierd if you go in the ocean at x1873,z593(right off the island) and sink down you will see a hole. In that hole is a mineshaft in a big cave system. be carful right when you get in there it becomes a water fall with a monster spawner right there. some parts of the mine are floating in the air. As far as island seeds go this one isnt to hard, lots of grass, lots of monster spawn at night, and a few more islands pretty close by if you need a couple more trees or just use the one on the island you start on.
