In reply to BeeDaurn:
Ledges from the smaller specialist suppliers - Runout, Fish, D4, Aiguille (UK based) overall seem better and more rated (+ have good aftersales for repairing/replacing worn parts etc.) than the overcomplex (heavy and fiddly) ones from the big brands. Simplicity is generally a virtue as bells and whistles can add to faff in putting up and taking down. Worth checking dimensions carefully though as if you're tall some of the lighter ledges can be a bit short. Beyond, a lot depends on your intended use - e.g. US bigwalling (generally good weather, easy hauling, few days, easyish retreat) or remoter/harsher destinations.
