ok, thanks for all your help guys!
I know I had major concerns when I had to ship an ElectroHarmonix 16 Second Delay (not the sturdiest of units) out to Italy in it's little wooden box! Luckily it got there OK, though :phew:
Because I'd changed my plans regarding delivery after the item had received bids, I couldn't remove the bit where it said 'local pickup only', so hopefully almost all of the people bidding on it, and hopefully the winner, will live local to me. I've only had two people contact me asking about delivery. So hopefully I can just deliver it in person...hopefully!
