Many of us got the 12' diameter one from Carrefour last year. About £65 IIRC, with cover, electric filter, swim aids etc.
It was a special offer, not sure they would have them again.
I find it quite ironic that the JPEG attachment is called small.
We collected one of these in the supermarket by the ferry in Caen for £55!!!! Still in the box ready to go though.
