This is a repost of my comment, and a couple of follow-ups (here and here) in response to a comment claiming a 'Fail', copied below.
Two good friends contributed off-line feedback:
- Just like buying a power tool. A good one last a lifetime and a poor one lasts for a couple of sessions with it.
- I'd phrase as: Professionals find it cheaper to buy & maintain expensive tools that JFW’s (Just Works), not a throw-away for every job.
- Sometimes I wonder if anyone actually gets the basics of network design and deployment. So many people think in the ultra-short term rather than in the medium to long term. Every dollar spent now saves potentially hundreds in the future when it comes to network design and deployment.
- It's the difference between buying a cheap TP-Link router and a Cisco router for business. One might last a year, the other will last a decade.
