I have more cordless (carpenters') tools than seems reasonable.  It may be an indicator of some mental disorder, but it's not hurting anyone...right?  For quite a while I would prioritize purchasing a tool that included a hard case, the drawback of this approach soon became apparent.  Yes, they provide excellent protection from getting knocked about in transport, but unless I was prepared to buy a pan-tec, the unnecessary volume they occupy would be crippling.
