I’m looking to buy one of the Graco airless paint sprayers, and I found them on eBay for significantly cheaper than anywhere else. I have never purchased anything from eBay and I’m a little leery of it. The thing is it looks to save me somewhere around $60-80, so I can’t ignore the option. I know to check seller feedback etc, but anything else I need to consider? I also know if I have a problem with it I will only be able to deal with Graco.
