I was given the second chance offer on ebay for a Luke I was outbid on and was wondering if I should get it. It is Luke blue, no piezo and no case for $650 plus 25 shipping. I already have a Luke w/o piezo and after initially loosing the bid I became interested in a Parker Fly on the bay (I have chronic shoulder/neck problems and was considering the light weight on that one). What should I do????
