I’d like to add a sump but I dont want to drill. I was thinking about adding a HOB overflow box. I would really appreciate set up ideas and good models and brands for the overflow box. Most importantly reliability.

Check this one out, https://www.lifereef.com/siphon.html
Solid piece of gear, great service, hand made in Colorado. I have been using mine for a few months now on a 55 gallon I couldn't drill, and am very happy with it.

The overflow you choose depends on the tank size.
Eshopps has the PF-1200 which is quiet and handles lots of water volume. Put you can pick a smaller model if necessary.

i have the cpr brand overflow on mine, and works just fine. i dont have anything to compare it to, so i dont know if its better or worse. i have yet to have a siphon break, even with water changes. Its been running going on 2 years now.,

Adding another +1 for Jeff at Lifereef.
Comments:
1. Don’t over size. If you’re running, say, a 75 gallon tank get the single siphon. This isn’t about being cheap, but that the biggest risk of siphon break is too low flow. Run a double siphon and you’re halving the flow. Even then - you can run these at very leisurely paces.
2. It comes recommended for soft plumbing with flexible pvc. Do this. It is cheap, fast and easy.
3. IMO a variable rate dc pump and adjust flow with that rather than adding valves. After you add the costs of all the valves and connections the dc pump is gonna be much cheaper.

Really appreciate the photos. I will consider this. Great to see how the setup should look.I use the following one from Amazon. It works pretty good. It on a 30 gal bowfront. Just be careful tighting the nylon screws as you can strip them out easily.
I also attached photos of my tank to sump set up
