Advice/Recommendations on EP3 Civic Type R Shock absorbers

[R-Mann]

Hi, I'm after some advice/thoughts....

I need to change the front shock absorbers on my EP3. Do I:

a) Replace with new OEM parts? If so, where should I get them from?
b) Replace with 2nd hand OEM parts?
c) Replace all 4 shocks with something different? If so, what should I go for and where should I get them from?

Thanks
