Sorry to ask this old question, but your collective pool of wisdom will save me a lot of time and money.

After selling all my 10x8 kit a few years ago, I'm now in the process of coming back to large format (cannot keep away) this time with 5x4.
Some of you may have seen my last post deciding on what type of Ebony camera to go for, I have decided upon a new SV45TE (folding).

I'm now looking for a range of lenses from 90mm - 450mm, I understand you have to buy the new version of the Schneider Super-Angulon XL 90mm for it to fit the Ebony?
I intend to use this camera for my fine art work of which is a mixed bag from studio close-up (no more than 1-1) to landscape etc. I have around £3k ($4750) to spend, happy to buy second hand for the right lens.

If you were buying again what would you do, buy a few of the latest new (I'm sure they are not a new design however?) or more S/H? What lenses are considered the best in your view.
