thanks, those in the ad would be perfect but a little too far away, Ill check in my area, thanks again.If you really want to find them, check CL in your area. The way I have gotten them is to "run across" them while working. I have customers in industrial complexes that have them. Look for large stacks of wood pallets, and check those lots. If they get routine shipments that cause an overload of wood pallets, they may get plastic ones in. Also check for international companies as these plastic pallets can be shipped back and forth overseas with no concern of infestation from foriegn bugs. I see these sold for around 5-10 bucks each on CL. If you have to buy them, it is a long term investment.
Here is an ad of exactly what i use and was referring to: http://hudsonvalley.craigslist.org/for/3333418338.html
