If you want another couple of sources for unusual fish, especially Apistogrammas, try these two;

Dwarf Cichlid Aquatics

Biddulph Aquatics, a UK source for dwarf cichlids

I have bought from both and can really recomend them for rare and unusual Apistos, great for planted tanks, and things like pencilfish and other unusual stuff.

On plants and other stuff I agree with Bob's recomendations completely, they're the ones I use!
