Just picked up a 3 cup Grosche Milano at HomeGoods for $19.99 but the valve looks very different from Bialetti's - is this how it's supposed to look? There is a sort of a hole with a screw thread that looks like it's supposed to have smth in it (it's not a through-hole as far as I can tell.). The pictures on Groschen site do seem to look somewhat similar but I couldn't find any with high enough resolution to be certain. The valve on my Bialetti looks distinctly different - i.e., no hole there at all. I just don't want it to blow up on me :p
