Airbag costs (working on a trade)

[BigMike]

Hey guys. I have a vinyl plotter I am going to be trading (hopefully) for some parts to bag my truck. I posted $800.00 or trade and someone came back with some parts he will trade for. My problem is I have no idea if it is fair because I don't know the costs involved. Can you guys give me a ballpark estimate to let me know if it is a good deal or not? I also have around 70gigs of vectors that go with the plotter, just about everything you could imagine.

Here is what he is offering - I can giv u all 4 bags, all brackets needed, air valves, switches and hoses.

Thanks,

Mike
