I've never had any bother from anyone on Basschat. But I do have some general golden rules. 1 is I never buy anything if I can't try it. 2 No bass gear I buy is sent to me through the post, I always collect, or if needed meet up with the seller half way between their home and mine, it only normally costs a little more in fuel that the post cost would be anyway, and I get my new purchase NOW !. 3 I don't buy ANYTHING from e bay over £50, too many rip off tales. Also if I'm selling anything I will offer to meet halfway with the buyer so that he can see the goods. All this restricts me a bit in terms of what I can buy / sell, but it works for me.
