Help I don't know which sbc to choose

Hello,it's the first time I write here I hope you are lenient.
I explain what I would like to do:
I need a SBC capable of processing inference at good speed
I found this:
https://coral.ai/products/dev-board/
$ 149
Now, the same house (Coral) only offers the module with the ml accelerator:
https://coral.ai/products/pcie-accelerator/
$ 35.
What I would like to do is find a less expensive SBC where I can install the module and save money!
The problem is that I can't find sbc THAT HAVE PCIE SOCKET,
I searched a lot on the net and came up with some Orange Pi or Banana Pi models
but they don't convince me much and I wanted to ask opinions from those who know more.
Do you have any sbc to recommend?
Budget 40 - $ 50
Thanks

You will have look your self on this site.

Regarding performance: You were not clear about anything measurable.

Regarding Cost: You said your budget. Things are not free, but since I do not know the purpose for your budget restrictions, I cannot comment further.

While I can tell you which SBC's I've used, I feel that's pointless because I have zero idea if a data pump of such and such clock speed and RAM will be sufficient.

You've mentioned PCIE extension. Hmm ... this seems important, I'll also say that it is specialized. So, ... is it important or not?

I've used various SBC's of various speed, size, and attachment capabilities across various spectra of consideration, each one performed as expected, because they were "right selected" for the projects they fitted for.

Meanwhile I have some number of modules, test boards, development platforms sitting around my office, because of the former evaluations as to whether or not something would be both: suitable, as well as easy/not to use as advertised.

I really can't offer much here because I don't know if you want to buy something to "play" with to make it into a home server, or if you're doing a one-of project, or if you're doing a prototype for a million dollar project where results matter, and the COGS matter, but also during prototype stages, they matter less.

Not sure exactly what you are wanting to do on yours, but I have a Raspberry Pi4B with 4GB ram, its quite a speedy SBC, (also comes with just 2GB ram a bit cheaper).

Maybe take a look at its specs to see if it's suitable.
