I shoot with a 200fe and a mix of C, CF, F, FE and adapted lenses.
You can download the manual, and use that as a guide to check that all the electronic and mechanical functions work properly. I do not know any way to get the shutter count.
I always wanted one when they were introduced (I was using a 500c) and now they are "affordable". I prefer to have a meter integrated, and welcome exposure automation when it is warranted. Mine (used) appears to have a pretty high shutter count, the plastic light baffle that bends with the mirror broke and jammed the mirror shortly after I bought it. I was able to get the replacement part from Hasselblad USA.
Batteries: the manual claims a ~1000(s) exposure meter actuations (can't remember the # exactly, but in that range). In practice, I have to replace the battery more than once a year. (On the other hand, a 2000 series runs forever on a battery...)
The 200fe works with all the V lenses. If you are using the waist level finder, I would advise not to meter stopped down with C/CF lenses, as the meter does not have a compensation circuit to read the light coming in from the waist level finder opening (unlike Rollei meters). The leakage is exaggerated when you stop down, causing the meter to read too high (under expose). Instead meter full open and set the +EV compensation to the number of stops down from full open that you set the lens too. By using the EV compensation, you can also shoot in AE mode, working with the lens wide open like you would with an FE lens. With the meter turned off, it works like any 500 series body.
The back shown is an ECC, it will work fine. E backs do not have the Zone setting dial.
The 200fe handles very nicely with a grip and PM5 (I have the PME51). Probably better with a 90deg prism (I haven't tried). But that makes the whole outfit pretty large - the hasselblad V's are very compact (for a 6x6), and the minimum kit (body, back, WLF) is very portable. Adding the prism & grip make it less so. So I've learned to use the reversed left-to-right waist level finder - which is not hard as I grew up using a Rollei TLR.
