Quote:
the new KGV will cost me around US$150. If you can point me to "just as good" in color for US$30, I'd be interested.

Opinion:
Given that I have not witnessed a KGV BW in colour, that part is my ignorance,
however
With KGV is see no advantage with colour
All colours are notated, it is then the experience / ability of the collector to ascertain just WHAT colour their stamp is.
No catalogue is going to offer that
Here are my colour swatches for the KGV
Try picking the Eosin Pink from your catalogue.
Notwithstanding, however, the gain you may get from updated information
with the latest Catalogue
By all means pay your $150
