From your original post and the comments following it, it sure looks like you want the RZ, which is changing the decision making process. If you want it that bad and can afford it, then you probably ought to buy it. However, be aware that you are suffering from a bout of GAS and giving in to it rarely makes it go away.
What do you want from an RZ that you are not getting from your RB? If there is a significant reason to have the RZ rather than the RB, then this could represent a chance to upgrade to the RZ with a little less money out of your pocket. If you are just suffering from GAS, well, then you are just suffering from GAS and will need to decide how to deal with that. Perhaps you should just buy the RZ, but I have a feeling you will be happier with your choice if you understand why you are doing it.
In looking at KEH, I see that the 50mm C lens for RB is $325 in EX and not available in BGN and the 50mm RZ in EX is $215. That is a big difference. However, the cheapest route, unless you sell your RB equipment, is to get the RB lens. If you are trying to convince yourself that the RB lens is overpriced and therefore you should drop another $350 to save $110, there is a hole in your logic. If you wish to get into RZ equipment, however, this is a chance to get into the RB rig (BGN rating) for something like $250 rather than $350, so it might represent a good opportunity for you.
