Hi,
I bought a 503CW on ebay and i bought at same time a sekonic 608 cine which does spotmeter and incident metering too, perfect for studio and outdoor, the 608 incorporate the aperture and time in the spotmeter, you don't take the meter of your eyes, for me it's the ideal deal than buying a PME45 which is not so helpfull like a handmeter.
For serious photography you need a handmeter, you can't have the same results with a incorporate metering, the best that exist is not efficient like a handmeter, i bought a 608 cine and very bulk made and waterproof and i'm sure that i got the right choice. Now if you want to spell money.......it's yours.
To richard, go to ebay site there are very interessing bussiness to do at the thirth of the official price!!.
I bought the 503CW here.
Sorry for my english.
