Monochrome / b/w same diff. Was referring to the lack of color.
Getting an approach certified GPS is the big benefit. I think there are lots of alternatives to the 530 such as the argus and even the kln94 which is a not bad price. Certainly the 295 is the best compromise for the buck if you want color mapping.
Have you figured out the switching arrangement yet? I think you should go for a five tube EFIS and be done with it. <G>
