6x7 Lens Recommendations

[Tom C]

I'm pretty close to wasting some money on a 67II system, despite my better 
judgement regarding the future of film.

I'd like some lens recommendations.  I know the 105 is a normal lens.  I'd 
also like at least a wide angle to start.  Is there any difference in build 
quality/image quality between a brand new off the shelf lens and one 
manufactured 10+ years ago for use on a 6x7?

Thanks,
Tom C.
