has anyone used one of these (weldcraft WP-150) or any of weldcraft's other modular torches? I work in automotive restoration and custom fabrication and getting into tight spaces and insides of stuff is day-to-day business around here, so having a pencil head w/ the flex coil would be really nice. I'm mostly wondering about durability. although most of the parts are pretty cheap (roughly $20 for heads and coils, $60 for the body @weldwarehouse) if they need to be replaced 5 times a year, then I'd probably be better off spending $80 on a standard 9-series pencil.
it's roughly twice that for the complete torch and 2 heads.
it'd be nice to be able to just change out the head, though, rather than changing the whole torch.
