BEI Mock community DNA

Hello everyone,
I apologise if I am posting this in the wrong section but I could not find one that seem completely appropriate.
I was used to include in the microbiome studies a mock community sample, purchasing the mock community DNA from BEI resources (product code HM-783D or HM-782D). Now these products are no longer available and they are not planning to replenish their stock. Is anyone aware of another company offering a similar product, or should I start to prepare my own mock community DNA for the future?
Thank you and happy new year!
