My subassembly tab is full of reusable lifters rated by payload mass and if i don't have the right one i'll build it and add it to the list. They're generally pig-ugly and covered in aerobrakes and a good proportion of the time things explode off them during re-entry, but I like the fun of trying to save a bit of cash from each launch. If I get one down fully intact within a few klicks from KSC i've got my hands in the air.
