ELEMENTALISH CHIPSET?

I've been trying to find a World Map chipset for rm2k3 with a lot of elements mixed in that blends decently. I'd like it to have desert or volcanic and iceish areas forests ect, just a big mix of elements with decent structures. Only ones I've come across don't blend well(or at all, sometimes coming out really bad >>) If anyone could point me somewhere that might help I'd appreciate it, thanks for your time.
