No OW?
Also, a straight price comparison doesn't really help much imo. Things like AUP etc make a big difference in cost/benefit. Esp when the products are priced within a couple of rands within each other anyway, then other things matter more.
Can't mybb set up a test station of sorts where each product is tested for say 7 days non-stop. e.g. Latency check & speed test every 2 mins. Then weigh the prices by the outcomes of that testing. Preferably with additional penalties for high std deviations & max deviations. NB would have to be a 100% clean line with nothing else running, no NTP updates, windows updates etc.
