If I know anything about this man he would avoid anything that stops him getting "all the power he paid for" And that said, he's just rung me to say he's trespassed the supplier and "warned me what a shady character he his". I actually know the supplier and warned him several weeks ago about doing business with 'menace', basically telling him that if anything goes wrong, 'menace' is the last person to shoulder any blame The skinny is this - he bought 4 panels and a tilt mechanism, all to be mounted on a garage roof. Now the council have told him he can't mount them there, so he's told the supplier to take everything except the panels back (unfit for purpose, blah blah) and he's therefore withholding the money for the mast etc. Supplier is not too happy about that, they had a deal and it's not his problem or concern where council will and won't allow mounting, as he didn't advise him about that at all Life truly is a cabaret sometimes isn't it ? ;-)) Joe --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
