Yes, it's really that simple.
Sell your old DCE flicker magic on ebay in the next few days (remember to post worldwide for the best price) and hope that someone out there has not heard of Jen's Schoenfelds new Indivision 1200 (or wants a flicker magic for an A4000) and you should get your money back.
The Indivision 1200 should be a lot better than the flicker magic. It's 24-bit instead of 16-bit. Reportadly works with more screen modes. It has scan rate conversion 50-60Hz, but I wouldn't recommend using a 50Hz mode all the time... the conversion will almost certainly suck ass for games and demos which scroll so switching everything to 60Hz will make everything look better.
