Enterprise 10G SFP+ switches has been pretty cheap on eBay for longer than that. While you can plug in an rj45 SFP it's just cheaper and better to use DAC cables.

Isn't the software (licensing) situation for second-hand enterprise switches bit iffy?

Second hand optics and preterminated fibre are cheap now too.

		First hand optics and fibre are cheap too really. I just picked up some 10GBASE-SR SFPs for $25usd ea, while an equivalent copper 10GBASE-T SFP module is nearly $90.
