lead tetraacetate

Hi folks,

After nearly a decade away from lead chemistry I am returning to my 
roots and doing some lead(IV) chemistry.  About <-that-> long ago we 
used to swear by Merck LTA and swear at the inferior product from 
Aldrich. About 2 years ago somoeone in our lab ordered a bottle of Merck 
LTA (CAS 546-67-8, old Merck cat number is:  8.07418), the stuff 
moistened with ~15% glacial acetic acid. It was/is good stuff but we are 
nearly out. I contacted Merck and they no longer supply it.  (The 
salesperson actually offered me lead (II) acetate as a "replacement" 
(Where do they find these people?)

Anyway, can anyone recommend a replacement?  Something you know to be 
reproducibly good as per iodometric titration etc...?  Any 
recommendations for brands to avoid as well would be appreciated. 

cheers,
Martin
