Which lambda sensor to buy

[tstapleton]

I have idling and rev problems with my 2000 saxo VTS. I had just put it on a diagnostic machine which come up with 2 errors: 1st error was a LIVE error with the lambda sensor, 2nd error was not a LIVE error and it was with the coolant temp sensor. The mechanic said to me to get the lambda sensor replaced first as this is the LIVE error and should fix the problems I am getting. So I have looked on euro car parts and found 2 different lambda sensors which vary in price by £40, the cheaper one is an alternative quality brand part as where the expensive one is original equipment manufacture (see link for parts below).http://www.eurocarparts.com/ecommerc...h_Results.asp#

Will I be ok to purchase the cheaper one or do you guys reccommend getting the original manufacturers one?

If the link doesn't work here are the part numbers:

710545170
