High Quality Printer for client proofs

I am a freelance graphic designer working from home and I desperately need to invest in a decent new printer. There are so many on the market I don't really know where to start looking. I need to provide high quality proofs for my clients as well as presentations and sometimes have to print on card and CDs. I already have a scanner and don't need a fax so all-in-one not necessary. Ideally looking for ink jet. Can anyone recommend a good printer? I have been looking at Canon's as I'm told they are less prone to blocked heads. Would really appreciate any advice.

Thanks!
