After quite a bit of comparisons, I decided to get the HIC printer, via Amazon. I ordered on Saturday, and I just received it (on Monday).
Here's a couple of pics of what's in the box.
Some parts are 3d printed, but none were broken, and seemed pretty sturdy. There are cast rails & fittings, stamped sheet metal brackets, machined bits, laser-cut bits, and lots of off-the-shelf bits. And a big bag of fasteners.
Haven't seen instructions yet, but I haven't pulled everything out. I'd heard that it takes a couple days at least to figure out how the thing goes together. I'm hoping to get some further on line documentation, or maybe you-tube help.
I need to complete a model project before diving further into this, but I'll post more when I do.
