Sypro Orange

has anyone of you experience with Sypro Orange for protein gel staining and
(stoichiometric) quantifications ?
I read of it in a recent BRCA2 nature article but wonder why this technique
is not much more commonly applied for all kinds of in gel protein
quantifications. Excellent combination of huge linear range, lowest
protein-protein variability, silverlike sensitivity and utmost simplicity,
fairly reasonable price seems to be pretty much unique among protein gel
stains or did I overlook any important practical drawbacks ?
Many thanks for your comments in advance !
best,
David
