I found a Green Botshots Brawl in a Charity shop for 20p last year. I also got a bag of kenner aliens so yes you find the odd cool stuff. - carboot sales are better though in general for cool finds.
As for the "Haul part" of this thread - I did finally just get an Animated Activator Fire Blast Grimlock and I also got a TR Power Master prime.
The strange thing about Prime's minion/head is I'm not really sue who it's supposed to homage is it Hi-Q or is it Orion Pax to some extent too - as the colours really are not like either of them but it does at least remind me a little of Orion Pax due to the face too.
Boy does that face look pretty silly on the Voyager Optimus
Been mucking about with different customs base modes - he's not to hard to make some much better ones with the options he has.
Hopefully sometime this year I can finally get an Ultra Magnus then I'll lend one of Magnus' guns to Optimus and the reverse so they can both have a pair of guns.
