F and A types have the best chance for ELWs so you may want to set your map to plot by them. Any planet you can land on won't be worth much (except a nice view) so I usually filter them out when I'm hoping to get rich. If you really don't plan on flying very far from the sun you may want to consider K type stars. I have a lot of luck finding terraform worlds in K systems.
Thanks for the tips, Denali. I'll do that.
This highway I'm on is pretty untapped, so maybe I'll get luck and find one my first time out
