Query: Don't buy this saw from Amazon

I originally bought this saw 11/2006 and they said delivery would be around 12/2006. Then they said it would be another month to deliver it, so I changed the address to deliver. Amazon ended up canceling my order in 1/2007. So I bought it again on 1/2007 and it was supposed to be delivered on 2/2007. Then Amazon wanted to extend again another month which would make it 3/2007, which I approved via email. When my dad didn't receive it 3/2007, I logged in to my account and Amazon extended it another month without notifying me! This was a Christmas present and this is unacceptable.I'm sure it is a great saw. It is a customer reports best buy. Just buy it somewhere else.
