If 2 channels are sufficient, you can probably get away with USRP B210s (which is expensive but superior) or LimeSDRs. You can also use a MIMO cable to pair up two USRP N210s together.
If you need more channels, things get a bit expensive. You will need to consider USRP N3xx series or hook up multiple SDR transceivers together. The cheapest way that I can think of is implementing your own master clock generator and clock divider (A bit riskier than using Ettus's Octoclock, though).
I would use LimeSDRs or XTRXs for 2x2 MIMO setup if it is a personal project. I would ask for more budgets (and take Ali Dormiani's approach) if it is a serious research funded by an organization.
(* Please note that devices like USRP B210 have one shared LO for multiple channels. That means you cannot physically tune to different frequencies simultaneously, but you get phase coherence between the channels. The MIMO Cable + USRP N210 configuration is the other way around.)

제목: [Discuss-gnuradio] Hardware for MIMO & Beamforming ExperimentHi dear community members!
I want to run experiments using MIMO and/or beamforming techniques with open source. However, I am getting stuck with hardware. Traditionally, I used USRPs N210 for experiments. I have only two.
Is there any cheap hardware that can support MIMO & beamforming applications on the market?
