i agree that sometimes its hard to get their attention, but other than that, im pretty okay with them. why NOT step into sweelee, they DO have a number of good deals.
If you can't get their attention, do what my friend does. Take a guitar and start playing, they will go up to you and assist you immediately hahaha. Oh and i say ishibashi as well.
900 for a warranty anit worth it. And they may give you the 'we cant do anything cos u spoilt it lala..warrantly voided' 900 can get u much more.
