    Samil Power 4400TL inverters going cheap - dodgy?

    A bit of a weird one. I've had a phone call from a guy selling inverters as he claims his company has gone bust. Selling Samil 4400TL inverters for £200. Sounds very suspect. Does anyone know of anyone that has had any stock stolen? He is ringing me back shortly but I don't have his number.
