Never used them personally, but they've been going a long long time now. I remember Athena big bore kits back in the 80s for the NS125, which as far as I know, were bored and re-plated 125 barrels.
Can't imagine them still being in business if they weren't at least half decent.
Everything 2-stroke we've had done in recent years has been by Poeton Aptec.
