Where can I get some cheap 3650s for home lab?

Looking to acquire a pair of 3650s for my CCIE home lab.

The cheapest I have found are ~$1k /each. Is there a community of hardware swaps or anything? I just would like to have a pair of the switches that I can borrow/buy (cheap) to maintain proficiency on things us wireless guys don't do a bunch (QOS, PIM, etc)
