Depends on the grignard you want to make.. Always best to make your own but i regularly use grignards from Aldrich which are so far ok.

yeah, but for simple ones like that its easy to make yourself, fresh each time for max yields. good practice too, for harder ones.

I'd use EtI instead of EtBr, its much less volatile.
