I'm continuing to procrastinate over the best home networking set up (it's been at least 6 months now). I suspect I know the best answer to this (the expensive one) but really feel like I should get confirmation.

Current set up is HG659 --> 8 port POE unmanaged switch --> 3x WAPs + various ethernet.

The immediate issue is replacing the switch. Half my stuff isn't plugged in (or is plugged in to the HG659 direct) since I don't have enough ports. The HG659 32 device limit is nearing too and that should be upgraded now/in time (I know I've asked about the router bit at least twice before but analysing *everything* to the nth degree seems to be my thing). 

I'm currently thinking 16 ports would be just enough for my assorted stuff/junk, so I really need a 24 port switch. I'm also sold on the idea of getting a managed switch so I can separate out via VLAN trusted stuff and untrusted junk (the WAPs already support multiple VLANs so can put wireless clients on to trusted and non-trusted VLANs too).

As I see it, the options are:

(A) 24 port, managed, POE switch - starts around $400. This is probably the best solution, but also the priciest and will totally clear out my budget for other projects. I also really only use the POE for the WAPs. CCTV is on the cards at some stage but as I understand it, most NVRs supply their own POE.

(B) 24 port, managed, non POE switch plus multi port POE injector - but no cheaper than option A and more clunky.

(C) 24 port, managed, non POE switch plus individual POE injectors that came with the WAPs - much cheaper (more like $200-$230), but will be cable proliferation.

(D) 24 port, managed, non POE switch plus keep the existing 8 port unmanaged switch just for the WAPs. From comments I've picked up on, daisy chaining switches can lead to network issues, and (I assume) will constrain the wireless <--> wired network connections to 1Gbps max since everything will need to go down a single cable. Would it make a difference between router --> switch 1 --> switch 2 (in "series") vs router eth1 --> switch 1; router eth2 --> switch 2 (in "parallel" - I know for the parallel one I would need a router with a switch; bad idea to use an EdgeRouter Lite with bridged networks).

Thoughts - in particular whether saving $200 but dealing with a mess of cables (i.e. option B) would be your go to? What about performance of A/B vs D?

Or option E - go blow it all on a fancy drill press and dither for another 6 months (happy  happy  drilling time).
