Problems with new ATI Ord Bot build

Greetings! So last month I purchased the Ord Bot mechatronics kit from ATI. The assembly was fairly straight forward but I ran into two big issues that I thought I'd share and see if anyone has any comments or suggestions.
The biggest issue is with the Delrin V-wheels. There is at least a quarter millimeter of play where the bearings seat into the pockets so the wheels can slide back and forth on the bearings. It seems like they shipped me wheels with about .5mm step but used 1mm shims. One of the wheels formed enough run-out that it quickly "polished" low spots in the Makerslide on my X axis. Which brings me to my 2nd issue.
The Makerslide they provided is not Anodized and has a soft mill finish. I keep the V-Wheels adjusted just tight enough to eliminate any play, but every wheels seems to pickup oxide from the Makerslide and eventually start building up clumps of it. Every piece of Makerslide was also cut about 5mm too short.
I contacted ATI several times to ask for help with the V-wheels but haven't received any satisfactory response. I eventually purchased a whole new set of V-wheels and a length of Makerslide from inventables to rebuild the printer. The Makerslide they provided is MUCH nicer than the ATI stuff, but unfortunately the wheels had a very similar issue. Inventables was great and sent a 2nd set of wheels so between the two I was able to get 14 perfect wheels to get my Ord Bot going again.
So I'm curious, is it usually difficult to find the Delrin V-wheels with steps that match the shim, or am I being overly picky? Has anyone else run into these issues with the ATI kit? At first $299 seemed like great deal, but in the long run I would have been better off buying the materials myself and getting the laser cut pieces from eBay.
Thanks!
