Searching for a (RC) Raspberry Pi 4 Model B 32bit. 64 bit Raspberry Pi 4 Model B's are everywhere

Hello! I’m new to the forum and I could use some insight. I have searched Amazon and Google for a (RC) Raspberry Pi 4 Model B 32bit. This is the model recommended by the main Home Assistant website. I’m having difficulty finding one.
Also I attempted to search this section (Hardware) of the forum first before posting this question. The search option didn’t work. It might be because I am new to the forum.
At any rate I am glad to be here and I would like to thank you in advance for any help with locating a (RC) Raspberry Pi 4 Model B 32bit.

Hi,
The 32bit mentioned on the HA website refers to the image only. The 32bit image will run on the 64bit Pi 4.
Hope that helps?

That is perfect! Thanks!

I have a 64bit Pi4 arriving today… I see 32bit is the suggested install. What are the issues on 64bit before I get started?

It’s merely considered ‘slightly’ less reliable as the 32bit version is very common and has been widely tested. Hence ‘recommended’

right on - going for 64bit!
