Best remanufactured oil pump balance shaft

[SteUK]

Hi all,

After some advice on the ‘best’ remanufactured balance shaft and hex key combo. My 170 sport estate has done just shy of 100k miles and it’s booked in to have the balance shaft and hex key replacement in a few weeks. Wondering which remanufactured unit to get. KMB now offer lifetime guarantee, but at approx £200 and you have to send your unit back to them...are the expensive option. ZD performance offer brand new units at £150 and no need to exchange. There are many more options on eBay. Opinions and thoughts much appreciated!
