If you're buying one think long and hard about the recoil pad, it's needed.
As for the wood. The samples they had there, which were I think the standard wood, were very nice. Finished in a soft oil look. Should be easy enough to maintain.
Ask them to mount sling swivels!!! Such a gun needs them.
And discuss the sight arrangement. Top rib should be drilled and tapped so a alternative sight, such as the Aimpoint Micro, can be easily attached. It's a natural for close work.
Last thing I'd ask them, at least for here in Fl where I'd use it for hogs and deer in the thick stuff is if I could get the barrels at 20 inches. Might make it look a bit short but then the regulating device on the end of the barrels already ruins the lines so go for function.
I'll say it again, a fine pieces of work and a great idea on their part.
