Cost effective direct out


My friend and I are starting a band where we want to have all the instruments go straight to the board. What's my best option for a cost effective direct out? I use a lot of effects and like my pedalboard as it is, but I'm not opposed to selling it off and buying a Line6 HD500. Any thoughts?
what's on the board already? might be fine plugging straight into the mixer depending on what's already there? as others have suggested it tends to work with an amp sim in the chain.
