DSOT Light Bulb Jacket Wooden Box Set Value

I have a delicate sound of thunder box set that came in a wooden box shaped like light bulbs on a jacket. It was found in my mother in laws garage. It has been stored in its original cardboard box, the cds have never been played but the wood box has been opened and i have the original recipt from its purchase in 94. I have no clue about this set. Is it valuable? Can anyone give a guestimate on how much it is worth? I searched the internet and cant find anything. Please help. Thanks

I saw it once (about 2008 in NY on a street-market if I remember right) sold at 250usd ... but I missed it at the time because of the costs... if you are interest to sell it, would be a pleasure for me ... it's the only info I have about, cheers
