It's interesting to note how some preconceptions can affect prices in a noticeable way, case in point: Tseng video cards. These (the VLB models in particular) are usually listed at insane prices, probably because of this prevalent notion (not just in this forum) that they are "the absolute best of the best", while there are many other cards that are just as fast (or even slightly faster) that don't have the same "fame". Especially considering that among all the "fast" VLB cards, the Tseng models are usually the ones with more game compatibility issues.
I think the problem in this particular case was that back then the Tseng cards were a great option not just because of the speed, but because they were considerably cheaper than the other "high-end" options.
Now, at this point it seems that all VLB cards seem to be considered "collector items" and they command absurd prices, but a few years back, this Tseng obsession, while annoying, also made some card listings go pretty much unnoticed, which allowed me to get for quite cheap a boxed Diamond S3 Trio64 VLB and a couple of Paradise Bahamas S3 864, which are all in my opinion more rare, just as fast and have better image quality than the Tsengs I have. So it's not all that bad in that sense.
