If you don't know what a "holy grail" is, it's basically that one item that absolutely makes/would make (if you don't have it already) your collection. It's that one set you've always been after and want more than anything. For me, my holy grail were the Bahrag, Cahdok & Gahdok. I never got them in 2002 and I most definitely wanted them ever since. Well this past summer I managed to snag them in an eBay auction, and though loose and missing just a few pieces everything was in excellent condition - even the instructions. (The pieces I replaced easily enough - which is fortunate since the parts list the guy sent with them indicated a whole lot more pieces were missing, which just wasn't true.) And I must say, I am definitely happy I bought them. They're a fun set and really stand out on the shelf in contrast to all of the later, much darker, large sets. So - what's your holy grail? ~|ET|~
