After discussions on this forum a few months ago about forum posters blocking him from bidding on their items, he no longer has any items for sale on eBay (TAS)!
But, wait! Who is this 'garbaco'? A new ebay member (11/1/11) already has 65 vintage HP calculating instruments and accessories, all at ridiculous Buy-It-Now prices and $5.95 or $9.95 shipping charges. And this seller is also from California! Perhaps this is a relation, one who shares the same genetic material with the 'big C'? Tricky, tricky, tricky!
So, for those who have blocked coburlin from bidding on their ebay items, you may wish to block his evil twin, garbaco, for the same reasons.
