The footprint and design of these look great. 15 pounds of materials is nice as well.
This, mainly Slaws. If these come in at $500 these aren't going to be competing in the same space as Crosswinds.
Seems realistic. Slaws are $550 base (add another ~$150 for shipping and PayPal fees for US buyers), so a $500 pricetag would slide them in comfortably under that.
