Which Expansion Tank for E46?

[daniel-5zjw7]

Hi All,

I'm going to replace the header tank on my 325ti as I think it maybe starting to leak and seeing as its a known weak point I want to change it anyway.

Question is as theres varying prices is there any make considered best or one to avoid? Looking at either a Meyle unit from ebay for £30 odd or one from euros which I think is Hella for £40 something..
