As for the cab costs, mine totalled, both cabs, to R1700 +- excluding labour off-course, which totals to 1 million dollars of money!
as it was my first build with many learning curves!
This is for the MDF, plywood, woodoc, paint and accessories to apply all decoration items.
So for R9k you can own some serious butt kickers with the advantage of building them to your aesthetical taste and requirements. You can even let management have input on the colour scheme, this will help by keeping them calm whilst you slave away in the garage.
And as I mentioned in my thread, anyone is welcome to come have a listen, trust me, you'll be surprised!
