The ggflex.com storefront was maintained by the other main dev for the project but he went MIA a week into our initial version 2.0 sales back in November. The storefront was locked by my request for 90 days but I couldn't keep it locked any further without his input since I'm not a site admin, so now it's taking orders again. I'm working to get that fixed, but it's oddly complicated.
I'm the middle man for all logistics and sales, so I've been getting orders just fine since the storefront went back up... it was just a bit of a surprise...
The listing there has a bit more customization (for the spindle type and extrusion color) given the options that are available in the storefront that aren't available on eBay, but otherwise the kit is the same... it's obviously also pricier, as it doesn't reflect a price drop that I put into effect once I started shipping and handling all the orders by myself. Should be a complete and up to date kit no matter where folks end up purchasing!
