I've bought an "outfit" and separate bodies/lenses from KEH before. I don't really think it matters either way price wise. You could also end up SAVING some money since you could pick up a lower grade lens for cheaper than an EX++ lens that may be part of a complete outfit. The real trick to KEH is that their BGN and UG lenses are actually really good. I recently got a 180mm UGLY lens for my RB67. It was dirt cheap, and it honestly looks brand new.
