Not as big as you would think Bruce. If you are referring to David's set-up at Hook Solutions, the cost is minimal in comparison to a professional set-up. No slam on David as I think he knows where I am going with this.
I have an electrostatic set as well and just haven't had the time to convert to it. A lot of DIY type stuff to fabricate to make the system versatile to your requirements.
The electrostatic spray gun can be purchased at Harbor Freight for $60 on sale. A used kitchen oven can be picked up for $20. Then there is the cost of material to make your racks and fixtures to hold the baits while you paint and bake them. And also the cost to make a spray booth which can be done for little $$. David has a fine example of how to do it, in fact mine will be patterned after his when time becomes available. The amount of racking he has is predicated by his volume requirements. If you are not painting that many baits then only a few racks would be needed.
Now on the other side of the coin there is the commercial electrostatic spray units that will require huge bucks to get into, a second and third mortgage and your first born as collateral.
This decision is really a no-brainer.
