The echinodorus I prefer are red special (because it has about 5-6 of the new leaves red), bleheri or amazonicus, martii (crispate leaves) leopard (small form and patterned leaves) ozelot (patterned leaves), uruguayensis (lots of tall ribbon leaves) and magdalenensis and tenellus as smaller foreground plants. I have all of the above and they are on Trademe from time to time. Many of the echinodorus here have come from tropica and are hybrids to osiris and get quite large. The ones I don't like are cordifolius,marble queen and the giant cordifolius (macrophyllus) because they grow so rank and all you see in the tank is the stalks (probably good in an open tank with metal halides). The one I would like but don't have is horizontalis because it propagates slowly and is not very commercially viable. I also have Hydrocotyle verticillata on Trademe (it is grown emersed but converts to submersed growth easily and is the only Hydrocotyle to remain in the media and not grow up to the light) Another good foreground plant.
