Suet Block Feeder Which Is Starling Proof

Hi All, can anyone recommend a suet block feeder that prevents Starlings from getting at the suet blocks?

I've had to purchase cages to go over all my current seed and peanut feeders to prevent the starlings from getting at the food so only the small birds can eat it. 

I get a number of small birds in my garden (Robin, Gold Finch, Blue Tits, Great Tits) but they get scared off by the Starlings who seem to stop by in large numbers acting like savages.

Any recommendations would be greatly appreciated.

Thanks
