CPR do custom work. One offs. To be clear, you hire an artist to create unique artwork (no copyright infringement) for PF, plastics, BG, cabinet decals, etc. So it isn't cheap and they won't replicate the same art, twice.
Anyway, if any of you are a lifelong Heavy Metal fan and are seriously interested and disappointed by the Stern offering, here is a link to a gallery of a conversion of a Firepower game to Heavy Metal. Get ready to drool....this one looks sweet (warning: MATURE content here!):

According to their pricing, I'm guessing ballpark you would probably be in the $8,500 range for the art *materials* to *do the rebuild yourself*:
1. Customer Re-Theme Option 2: $3,000
2. Custom cabinet decals: $350
3. Custom topper: $90
4. Plus custom artwork: $5,000(?) -- depends on the quote, which depends on the artwork you want done
Please note: I am not connected to CPR in any way. I did do an evaluation of what it would cost a few weeks ago at the prompting of a friend...because I have a Firepower; he is a rabid Heavy Metal fan; and this looks incredibly good (would look killer next to my rebuilt Centaur). But I'm skipping, it's too much $ for my tastes since I'm not a true HM fan.
