camera crisis

My nice big camera has been acting up a little lately, I even took it in for a tune up but it really did not fix it 100%. The other day I was just taking some pictures when it completely died. I took it in yesterday and it has to be sent out to be fixed and that could take weeks. I do not have week we leave for Hawaii in less than two weeks! Talk about bad timing. I just ordered the d90, I'm very excited for it to get and for me to figure it out before we leave. Hopefully the can fix my old one and then I can sell it. In the mean time I'm dealing with the little camera that just does not cut it.
