It's definitely a pricey device and I would never have paid the price for one, but I ended up spending about $25 bux for the parts to build one from directions that were found on YouTube. I don't know if the same directions are still available, but plenty of others are still there for those who don't mind making their own. I didn't want to scenic my RR with fields of grass, but preferred just adding static grass as an accent here and there. The homemade static applicator works well enough for that.
