I've used Analogue Wonderland, FilmDev, AG Labs, all with satisfaction. Now I mostly have gone back to dev and scanning myself for b&w, only sending off colour.

Or if you want to spend money, Intrepid sell nice colured ones for their field cameras, or there are similar on ebay for less. I have a nice blue one and a bright red one! (both double thickness with black liner)

Sorry to hear of your problems with WYC; I've bought a few large format lenses from them and all have been exactly as described or better. Maybe I've been lucky or you unlucky?

A lot of very nice shots there, some lovely colours too

A lovely set, the mono ones particularly nice but I like how even most of the colour ones are very monochromatic except for isolated splashes of colour, that is really well composed.

I am thinking of a London trip, funnily enough, I was thinking to stroll around the City on a weekend when no-one much is working there, but with some great architecture. Also visiting old work locations (not so nostalgic about those!). And the South Bank.
As a contrast to the kit mentioned, I've just acquired a Zeiss Ikon Nettar folder with a lovely attached rangefinder that needs some exercise...

I did wander around that some time ago and found it decidedly unphotogenic. I might have a bash though with a tilt-shift lens I bought (Astrhori 50mm) for my Olympus M43 kit, that I guess I could mount on one of my Pentax cameras (I'm thinking the LX actually) with an adapter.

The range of viewfinders for the LX is brilliant. I have several including the waist level one, they are an extra facet of the joy of the LX.

and a slightly abstract one whilst wandering in Northampton:

I was lucky enough to get mine (from Clifton Cameras in the UK), and it's a joy. It has brought me back to Pentax whilst still having Nikon gear (D500 & D850) and in practice I'm finding the menus and controls far preferable. So it may be the thing that grabs extra market share and will encourage new users into the fold.
I can't claim to be good enough a photographer to justify the £2249 it cost (plus one lens so far used for £400-odd), but fortunate to have the income at present to indulge myself.
