Can you confirm that the bearings should be dry - with no lube? The bearings I am looking at on eBay are:
3x8x4 Hybrid Ceramic Stainless Bearing Lube Dry S693C 2OS A7
3x7x3 Hybrid Ceramic Stainless Bearing Lube Dry S683C 2OS A7
Also the relevant parts section lists just the 3x7x3 and not the 3x8x4 bearings.
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
