I have been ordering small bags of Envigo Teklad blocks from eBay for years. Suddenly there is no such thing except for one vendor I've never seen before who has only one 10 lb bag for $79!

Does anyone have any info on whether these blocks are still being made? I'm starting my five littles on Mazuri but not at all happy about it. Envigo was shut down after the beagle fiasco and a new company took it over which seems to be strictly involved in laboratory testing etc. No luck on Amazon either. Halp!!
