from what ive handled of the carvex, it seems just a more expensive trion with a disco light on it. I own and like the trion and so no need to upgrade to the carvex. the only thing I like about the carvex is that awesome trammel arm, which festool made cleverly incompatible with the trion If iw was in need of a new jigsaw right now I'd fork out for the mafell, but for now I'm fine with my trion
