oh my goodness why do people tell lies when it is so obvious they are lying?!? I'm glad you managed to get it cheaper after that!
It sounds like you're being very thorough with the cleaning (I don't blame you, I would be the same!) and I can't imagine anything nasty would still be living on it after all that but I'm still a newbie so I'm sure others will have better advice.
I'll look forward to seeing it when you get it up and running and I'm sure Blacky will have lots of fun with it
