I very rarely (these days) post anywhere other than the classifieds because my home circumstances have changed and I don't have the time any more. I used to post a lot on the old forum, and I'm a subscriber, so does that make it okay or not okay?
I also tend to put stuff on here first before I have to go through the hassle of Ebay. I agree with the posters who've said they buy, use then sell, sometimes for a bit more, sometimes the same, sometimes less. All depends on what you're selling, what time of year, who's watching etc as to what price you get. There's nothing wrong with buying something with the intention to use it then plans changing, or using it for a while then reselling.
Some people do need to get a little bit of perspective I think.
(note to self, don't post OT stuff on forum so much...)
