I have a Debut III. You can usually get these from NeedleDoctor for at least 10% off list if you ask. Also, They run the gloss white on closeout from time to time. I picked up mine for less than $300 a few months back.
That said, the Debut III is NOT compatible with MC cartridges unless you upgrade to the acrylic platter. If I were doing it again with the Debut III, I would either upgrade the stylus to the Ortofon 20 series or have NeedleDoctor swap out the cartridge for an Ortofon 2M Red.
Also, with the Debut III, the SpeedBox II makes the table sound significantly better. A pretty cheap upgrade when the time comes.
So, I would do the following:
Get a DebutIII and bundle the stylus upgrade. You should be able to get it for around $450. Take it out of the box, adjust the arm balance and tracking force and you're listening in 5 minutes!
Don't forget the usual accessories: carbon fiber brush, stylus brush, and a bunch of LP's.
