Well, the only SC Sig Deluxe I have in the sold database went for $3298.81 (actually a UK sale, for 1800 quid) via a Buy it Now. This was after it had failed to attract a bid that that price for about 10 days. Nothing unusual about it; a basic Deluxe version, w/Signature electronics and no extra bells or whistles.
I have another one in the db that didn't sell for it's opening bid of $5500, and which was withdrawn because of an error in the listing before the auction ended (and the seller has subsequently left eBay). This one had a stinger omega upgrade.
I have three in the overall database that are for sale through Bass Central. These are new basses, being sold for about 25% under retail. Two are selling for $6980 and one for $7675. (Note that Bass central has more than three available; those are the only ones I could discern the serial numbers for).
Now, there was also a SC Sig Standard that sold on eBay back in January, that went for $3500.
So that's what pricing info I have. Based on that very meager info, I'd say that the $3095 deal could very well sell on eBay for that or a bit higher. But I tend to agree with yggdrasil's viewpoint, especially if it turns out that the bass needs an electronics upgrade.
