when i bought mine a year or so ago these were the best price & new stock http://www.southyorkshireairguns.co....rging-18-c.asp

Do check on the manufacture date of what suppliers are selling, you can loose 6 months easily, so cheap is not always best buy

My 12 lrs is now some £25 more £s, also bear in mind the cylinder is supplied MT so it will req a full charge locally
