Hi guys. I'm new to all of this but I work in the marine industry in the UK. I've just been offered 18 CTL mini extractors that have been smoke damaged....they all need a really good clean but all are working fine. One or two are showing some battle scars...broken bits of plastic mainly. I was wondering if anyone can tell me if they sound like a good deal. I can have all 18 for £500. Thanks in advance.
