Yes, I've got a lot of help, so ... thank so much
As I've seen on the given weblink, the DNAzure stain is sensitive enough, but after the electrophoretic run need the stained gel a strong (and possibly blue ) illumination to make lanes visible ( e.g. with IORodeo blue transilluminator ), so 1 plus for blue illuminator. If I buy a blue transilluminator ( what as I've seen, it is fully optical and size compatible with the IORodeo electrophoresis equipment), cheaper option to buy a UV/blue fluorescent dye and use them together. DNAzure sexy, but a bit more expensive, and needs sg. extra place and money( to buy and store at least a strong blue-rich light source or a blue transillum. to develop a visible lanes). At this time me looks better ( and if I summarize that cheaper) option to buy a blue TI plus blue sensitive GreenView stain.... but if the development of DNA stains keeps so quick, maybe few months later comes something one-step stain, that needs no extra developing process to make lanes visible, and then become the white illuminator better choice ... who knows...
