Getting back. Just trying to use budget machine for home practice

I used the DDJ SX-2, sold it and stopped DJ-ing around 2 years ago.

I am currently living in college dorms and have kinda limited space to build a setup table, so I am just trying to get something smaller and cheaper (preferably used) and something that does not require laptop just like the SX-2 as it would take more space.

The XDJ-RX2 is nice but way above what I am willing to spend. Even the XDJ-R1 is kinda pricey so I might just go for the used version. Any recommendation? I would also consider other brands that may cost around $300 used.
