Finding that the great thing about eBay is finding those things you've dreamed of having, and someone else wants rid. An example is the Airfix Bloodhound missile, if only to go on the desk next to my Seawolf.
The kit was re-released recently, and I never got round to grabbing one. But there's been a few popping up on eBay, so it's just been a case of waiting and making a bid 
Noticed recently that Frog, another plastic model manufacturer, did a 1/25th scale version many moons ago. Bigger and more impressive a desktop model, you'd say Well, have a look at eBay to see how much it went for 
:
Don't think I'll be buying one soon.
I bought the Airfix Bloodhound from EBay recently, I didn't realise it had been re-released. The ones I'm waiting for are the 1:32nd car kits from the 60s and 70s.
