TP-Link Archer C6 v2.8 support

Hi all, new to this forum and also in OpenWRT world. I Am thinking to buy a Archer C6 router. But the supporting version by OpenWRT is v2 but in my country (India) they are selling v2.8 and also not mentioning if it is EU/RU model or US/TW one

Any has any idea about it? Or should I go with Archer C60 or Archer C50?

Buy it in amazon they are selling v2 EU models only. i just purchased it today.
