Yeah, at no point should the "something interesting" be a gray level 10 item. It's a time consuming process that should never return garbage for a successful search. I can understand not filling up peoples inventory with greens and blues, but for crying out loud there needs to be something for the time spent.
I didn't mind all the blues and greens to be honest. I'd spend time out there looking, fill my inventory, call out my vendor droid sell it off for a bit, and keep looking for speeder parts and armor pieces. While I could spend the same amount of time making more credits but for an hours worth of searching I'd still make 100-200K or so. Made it more bearable.
