Agreed, Paul @walshy bought a Modulus Flea from me a while back, sold it on and had the extraordinary decency to not only tell me he was going to do so but to send me, in cash, the difference. Walshy also plays a very act role in the community and has on many occasions helped me and other out with purchases etc, in fact he was only last week hunting down a very specific instrument for me, you'll never guess what.........
There's a few others on here I won't name who do not work that way sadly
I was tempted a while back to start a thread listing basses sold on BC that are a) now for sale at an inflated price and b) not for sale on BC, the main issue for me being less the inflated price-tag but the fact that the new owner is often trying to hide the mark-up by not selling it on BC and thereby opening themselves up to comment in the thread. I thought better of it as I imagine it would have been locked within days, but as Lawrie @Burns-bass says above, all that happens in price inflation which does no-one but the dealers any favours.
Still, it would have been fun to point out some of the bullshit, the 'my trusty old Precision' bollocks about an instrument they've owned for less than a week and possibly never even played
