Whats it worth? Neo Geo PULSTAR soundtrack

[PTL]

Hello all, I'm hopeful someone here can help me out..

In recent months I have been very interested in buying the Pulstar soundtrack. It's a very rare disc and I now finally have the opportunity to buy it. However, the price is quite a bit higher than I was expecting even with it's rarity.

Has anyone here ever seen this for sale? Maybe someone saw one on eBay? Perhaps someone located in Japan that frequents the shops? I'd really like to get a fix on the price for this thing before I plunk down the cash..

This might be one of my favorite game soundtracks of all time, but I'm still having a hard to justifying the purchase. Any help would be greatly appreciated!
