dang you really haven't been looking online huh? It's true that blazer valks have been going for a lot, but all the ones I've seen lately have been pretty cheap and all under 90. I even got my lot for cheap, VF-17S, VF-17D, and VF-19S all unstickered, unused and minty condition. Here's the auction:
Mac 7 auction
And even before that, I was kicking myself for not bidding on all four that ended at $99.99, with just one bidder. Total with shipping was 120. But I don't know if those valks were unstickered and minty like mine. So there's your challenge. I even know where I can get a VF-17D and VF-19 fire Valk, both unused for 50 each + tax. I think that's pretty damn good for the VF-17D, but I don't know about the VF-19 fire valk. That I've seen go for hella cheap on ebay, because of the bootlegs. Even back in 1996 when they first came out, all four valks were at 4800 yen or so. So about 50 bucks each, and then add in the shipping. Stores here had them for about 80+ for each one.
Anyway, about the blazer bootleg. I bought one back in 98 when they first came out for 25 bucks. My bootleg was pretty much identical to the original blazer valk, paintwise. But the difference was it was the fire valk body painted blue. The head was the same. I'd say pick up the bootlegs and worry about the originals later. The only ones I'm missing is the Fire valk, VF-17D/S special coated versions.
