Engine mounting (Front), Insulators: OEM or Aftermarket?

[Greek Cruiserhead]

Hi folks,
looking for engine mount Insulators for my engine swap: one can choose (here in Europe) between OEM (200 euros/piece) and Aftermarket (for as low as 45 euros/piece).
I wonder if this part is not a cosmetic one and OEM parts are worth the money spent. What do you think about it?
Any contribution is welcome!

I recently purchased a pair of these and was pleased. My theory is that @cruiseroutfit would not offer them if they were not of very high quality.

Pic of the aftermarket part is just an example.
Found that Insulator as a YS part (made in China) for that price at ebay, no idea about their quality though...
