My first E Bay purchase (and last) was a couple of years ago now. I bought a Violin for £50 buy it now , advertised as 1 thing (google confirmed new price circa £200) but when delivered was something else (google confirming new price £50).
The instrument just wasn't what was advertised. Invoked the dispute process and got my money back, but left him a few choice words in the feedback section.
This is a much better, friendlier place to buy, trade your gear!
