What's the price? The Agent is a pretty decent board, but those Tech Nines are garbage.
I'd just look the board over really well. Check the edges, check the base for damages or poorly repaired damages, check for delamination, make sure the camber hasn't been ridden out of it, etc.
Considering you're still going to need bindings, I definitely would go over $75 for the board, then you can grab those Ride MVMT bindings off of the For Sale forum for $40 and there ya go.
Not a fan of Ride bindings, but for $40 you can't go wrong.
