Another word of warning re Rocky, the last time I bought cameras from him it was a complete nightmare.
I bought 3 cameras from him, an OM4, a Voigtlander Superb and an SX-70 advertised as a spares or repair. The only one described remotely accurately was the SX-70.
I contacted him immediately about the Superb as it was, to use a technical term, completely shagged, I got no response despite repeated emails and phone calls, in the end I too resorted to raising a Paypal dispute, he then responded with " why did you raise a dispute, if you'd contacted me I would have sorted straight away" He eventually agreed to swap the Superb for another he had in stock, it arrived and it was a much better copy but then he got stroppy because I wouldn't close the dispute until I was happy that it not only looked better but was fully working as he described. For a man so slow to respond to his customer's attempts at contact he's very quick to whinge about it when the boot's on the other foot.
The OM4 which he described as fully working and in Exc++ condition had a sticky shutter, so rather than sending that back I stuck it in the post to Miles for a CLA, unfortunately it didn't just need a CLA, it was beyond repair since the circuit board needed repairing and there are none of these spares still available, certainly in the UK.
Despite my repeated attempts to contact him over the past 6 months he has ignored all avenues of communication, Paypal are no help since it will only deal with one dispute per transaction.
The SX-70 was, as he described, completely shagged and only good for spares or repair, it served its purpose.
So, if you are tempted to buy from Keith Rock here are a few recommendations:-
1) Ignore his descriptions, they are meaningless.
2) Always take a screenshot of the webpage of the item before you buy it, as it will disappear once you've bought it.
3) Always pay by Paypal, any other method is asking for trouble.
4) If you have a problem with an item, send him one email to register your dissatisfaction and then raise a Paypal dispute as soon as you can after that.
5) Check whatever you buy from him quickly and very very thoroughly, It wouldn't surprise me if he buys his stock by the kilo and there appears to be no quality control at all.
6) Be prepared to be disappointed, frustrated, angry and thoroughly tinkleed off if you have to try and deal with him.
7) Be aware that although it may appear to be a bargain it might turn out to be a complete lemon.
8) Be aware that although it may appear to be a bargain it might turn out to be a bargain.
I'm not for one minute suggesting that Rocky's Cameras only sell tat as other's experiences show that that is not always the case, but buy carefully and don't throw away the packaging until you're happy with what you've bought, at least then it will only cost you the return postage to get your money back.
Caveat emptor
