Which USRP is the cheapest for self training?

[Tepig]

I'm going to purchase USRP for my RF self-learning. I have a little knowledge of RF but is not enough for actual job.

I'd like to begin RF fundamental and finally, understand 5G/6G.

As a begin of my project, I'll take this training resource --> Lab 1: Introduction to the USRP

I do not have specific goal but wish could communicate with PC via wifi.

Because this is my personal project, I cannot purchase the highest grade of USRP. For example, USRP-RIO is too expensive.

But I also have a concern, is purchasing USRP-2900 which is the cheapest one is the best choice?

I'd like to ask RF specialists which USRP is the best to learn above concept?

Also, do you know interesting application or resource which suitable for self-learning?
