anybody tried the iMac 21.5 i3

OK, I understand. If each has its Airport turned on (wifi) and Sharing enabled (System Preferences > Sharing) then you should be able to transfer from one to the other. If you have an ethernet cable or FW cable, you can connect them with those as well. Ethernet would be the fastest (gigabit).

If you have a FW cable you can put one in " Target Disk Mode ".

Read up on it here ....

Read and heed all the warnings .... i.e. make sure all software and firmware is UP TO DATE !!!!

TDM is really unnecessary now that Macs support network connections over FW.

Just make sure the files are in the right place. Either the users PUBLIC FOLDER or another set up to be SHARED.

If nothing is in the users PUBLIC FOLDER and no other folders are set up to be shared, you won't see a thing.

We do massive file movement over the network on a regular basis. All of our backups are done via the network to a raid array setup for backup purposes, and then a copy of that backup is sent over the network to a secondary backup system not on-site.

I've never really used Target Disk Mode, but I wondered since the OP was looking for options why not offer up one that hasn't been offered up and relatively easy to perform.
