The other thing about the big squirrel buster, is that it holds about 3 kg of sunflower seed hearts and it doesn't clog up. It last a couple of weeks without filling, so if you go away , the birds still get fed.
I think that if you work it out per year, the metal ones work out cheaper in the long run. I found that cheap ones only lasted days in some cases. They were then chewed up, dropped on the ground, and dragged into the woods. The first year I spent a lot on plastic feeders. Forget the net bags of nuts, they shin along the washing line and drop the lot on the lawn.
