Dude, given the rarity of those cards I don't think the pricing is that unreasonable; expecially given how many of the accelerators that were produced have since died or developed faults.
If you want the price to drop, you can buy the rights to produce the designs from DCE and start your own production run. Until then expect price rises on these things to happen again in the future as they become even rarer.
P.S. Multiple smileys, exclamation marks, question marks and ALLCAPS are really fscking annoying and encourage people to take you less seriously.
