Just a word of warning, and I say this from my position as a multiple repeat buyer from Ffordes. My only unsuccessful purchase from them was a Rolleiflex, which I paid about £600 for (can't remember which model it was, a 3.5E I think). I was disappointed with its cosmetic condition (think it was listed as EXC+ but was quite ropey looking) but moreso its functional condition...the shutter was clearly a bit sticky for one thing, and the lenses weren't tip top either. And I think they said it had just been serviced....
On the plus side, I returned it and got a full refund, no quibbles, so this is only a minor complaint really, but I was a bit disappointed that it clearly hadn't been checked very thoroughly, especially given the price of it.
Now as I said, I've bought loads of other stuff from them and have otherwise been very happy with the condition of items. Just made me wonder if Rollei stuff is often oversold in this way... and I felt as though I'd had my fingers burned with getting involved in this premium branded photography lark!
In a similar way, though at the opposite end of the price scale, I bought my Rolleicord from the classifieds here, and it was also a bit ropey - one of the feet pushed in, and also with a sticky shutter, yet it was described as having no faults. I got a partial refund on that one, which helped pay for a great Brian Mickelboro service, but it also gave me the impression that it's hard to get a good Rollei!
Maybe it pays to go to a dealer who specialises in them (I'm not sure who that is though).
By the way, now that it's been serviced, I love my Rolleicord and would heartily recommend it....if you can find a good one! I still have a vague yearning for a 'Flex, but in truth it would make no sense for me to 'upgrade' at enormous expense.
I'm not sure about the T, some people swear by them, others sneer at them. I don't think it's any improvement over a 'Cord though, certainly optically, yet usually commands much higher prices.
