Marcio,
We're still at it, $40 per cylinder for any of the soft top cylinders and $15 total for return shipping via USPS Priority insured mail per order. We normally have the cylinders repaired and back in the mail the day after we receive them. We warranty the seals we replace for 3 years.
Make sure to check all of the cylinders carefully for signs of leaks. MB used the same seal material in all of the cylinders so they deteriorate at roughly the same rate.
