[Dangerous Doug]

For the materials you will need to buy, and any parts you will need to have fabricated, I doubt any vendor will give you a volume discount on "two". I suspect most of the Cobra manufacturers (FFR aside...) do not manage to get a volume discount on their relatively moderate volumes.

I think if you want to scratch build, you almost have to do it out of the sheer personal pleasure, rather than economics---scratch building will cost more in money or time.
