It’s an old kit, but it does get re-issued now & then. I think it’s currently OOP, so eBay is likely your best bet. Bids can vary wildly on ebay, so keep your eye out for one in your price range.
Agree with Rick. Don’t give up on ebay so fast. Try to find one going off at an unusual time (midday, or very late at night). Mid week also helps, when fewer people are online than on the weekends. It may take several weeks, but I’ve seen auctions within 24 hours of each other vary by 50-75 percent in selling price for the same model.
Of course, if someone here has one for a bargain price, so much the better! [:)]
Keep an eye out for it, might take some time but good ole eBay can occassionally provide a sweet deal. I was in the same boat for a Williams Brothers B-10, took a couple months but finally picked one up for 3.99!! With four others on auction simoultaneously that went for 15-20+ each.
