+1, don´t take one statement too serious, please.
Hobbies like ours rely on invention and investment, like many other hobbies do as well. IMHO, it is shortsighted to be against this kind of cool experiments, as they also build up crucial knowledge to fix the original cards. Backfire´s resurrection and repair clearly (and scientifically) now analyzed that the end of useable lifetime for all unmodified Voodoo (VSA100 and others) cards is close. Furthermore, improvement like his new power circuitry help preserve original cards and might in conjunction with Anthony´s solution result in even better future circuitry. And as in any other hobby, that depends on real experts showing up, analyzing and solving (!) problems. Imagine, no old timer car would still be around, if one would rely on original spare parts (i am not talking about brake pads here, but even hand carved cylinders/blocks) and in-depth reconstruction and engineering.
In terms of pricing, the V5 6k would have been the absolute flagship of this time and the V5 55k was 250€ (500DM) in stores. Price for a 6k back in 2000 was supposed 600$ (with 2% inflation correction over 20y that would be 910€). A price of 1500€ for Anthonys cards today is thus cheap and in my eyes totally justified for expertise, materials and especially with regard to what collectors pay for the originals.
And in the end, as GAT always points out: It´about the 3dfx gaming experience, which unarguably can´t be guaranteed without surgical help/improvements anymore without risking the originals.
