I've been looking at these chinese fiber lasers awhile now and I think I'm ready to pull the trigger. But I try to be cautious when buying anything like this from overseas.

Right now, my thinking is to go with one with a 50 watt JPT laser source ( the 1 to 400 khz freq) and a 175mm lens. Or possibly 30 watt. Most of my demand is for steel, aluminum, and brass engraving. But I would like the ability to mark (not necessarily depth engrave) some plastics.

Is SFX a reputable brand? I see their stuff advertised on aliexpress, amazon, and ebay.

Also... if I buy it on any of those three platforms, what happens with customs? Do I get a call from US customs to drive down to houston or san antonio and hand them a wad of cash for import duties or what?

Sorry for the dumb newbie questions.

I've been co2 engraving wood for a few years now on my trusty old epilog legend 32, but its time to expand my capability. Had to turn down enough jobs that its hurting me more than the expense of a new machine will.

Any help ya'll could give would be most appreciated.
