Hi ! I'm going to buy a used cornet on ebay uk but don't knwo what's best for my £100 budget. Actually I'd like to get a Boosey and HAwakes or a Besson, old if possible but in quite a good condition. The thing is, sometimes I see 2 similar cornet (for me) but one has got loads of bids and the other one doesn't... so what makes the difference ? Is thare an important point I'm not aware of ? Thanks in advance for your help.
