$40.. I haven't used it much but it works fine. I have no experience with other Samsung phones, since I had been using Blackberry or iPhones until my current S23+, but it works fine with the S23 series and I just use a Logitech multi-device keyboard and bluetooth mouse with it; but nearly any bluetooth keyboard/mouse or corded stuff with the dock should work fine.
Here is the keyboard I use for my S23, current gen iPad, and my Macbook Pro. https://www.amazon.com/Logitech-K380-Multi-Device-Bluetooth-Keyboard/dp/B0148NPH9I/ref=sr_1_3?crid=34P0TEB50870V&keywords=K380&qid=1684099958&sprefix=k380%2Caps%2C196&sr=8-3
My wife and I have a motorhome that we travel with a few months out of the year, I specifically switched to the Samsung so I could just use Dex on the big 55" TV in the MH living room. I use Superhuman for email and they are coming out with an Android version in a couple of months, so the upshot is - I'll really just need my Samsung, the dock, and the keyboard/mouse most of the time to keep up by my horrendous volume of business email. I'll just use the big 55" 4k TV as my "meetings and email" monitor and leave a lot more of the gear at home. By using the phone, no need to screw around with hotspots, "tethered" dataplan limits, etc.. and we'll just do the same for Netflix, etc.
Have you seen thr baseus dock? It is also compatible with Dex.
