Impreza expansion tank

[edar]

Can any one advise where I can buy a new expansion tank for my 03 WRX? Mine eventually popped on Sunday and I've had a spare fitted but that's also starting to leak. As usual parts are ruddy expensive so I've tried ebay and found one for £100. I'd rather not pay over the odds, so if anyone knows, or has one for sale, for a reasonable price I'd be grateful for the info. Thanks.
