I would look at the Behringer X series as you really do get a lot for quite little money. The X Desk is 8 faders and works great with PT. I only seen and tried it at music messe but i know t is NOT old Behringer crap. Since they bought Midas it has become a whole new ballgame and the X series are easy to install and works great, feels good/great but no meter bridge if thats important to you.
Then I would look at a used C24 or the Presonus Faderport 8. It is supposed to work with PT12 but I can not say yay or nay as i never used it.
The Q-con is good value for money too but i never been keen on them for some reason, we only have used the ICON series and now we run our trusted SSL4000G+ 48 channel and two Slate Raven MTi2 which are a revelation
