Just a note on that:
Read the actual full document from the website, not the summary table in the article, DC is listed in the full document. On there you'll see they compare the cheapest
384 Uncapped
512 Uncapped
Now, DigiChilli's cheapest uncapped offering is 256* (not 384) and their 512 offering is actually more expensive than Screamer (Screamer being the cheapest there with R799 vs. DC's offering of R1000).
*Note it is now "Up to 256" not "Minimum of 256"...they changed that wording

.
That said, i do not see SAOL on that list with their R500 uncapped 384 "all inclusive" offering...or was that offering a limited special?
