Electronic Grinder

Hi everybody,
 
So first of all just wanted to say that this is my first topic, so i really dont know if im asking this question in the right section.
 
My question is this, most of you surely know this type o electronic grinder, 
Last year i went to amsterdam, and once there i bought a Electronic Grinder, much like this, but it had one more part, to store crystals, wich made it waay better, because it would store a lot of them (basically every 3/4 days i would have a pure crystal joint), unfortunately a few months back I lost it and ive been searching for another one like it ever since, but i cant seem to find it... i can only find these 2-part electric grinder...
 
The store where i bought it wasn't a "Weed smoker Special store", just a normal random store, that sold every type of stuff aimed at tourists, so the grinder i bought isn't a special one made and sold by a specific store, i think that they are surely made industrially (it cost 10€)... but i cant seem to find them anywhere.
 
anyway, what i wanted to ask is if anybody out there knows what im talking about, and if so where can i find/buy another one...
 
Thank you

 

hey dude, thats the one i posted lol, i want one with one more part to store crystals, it has a metal opaque part before the plastic see-trough thingy
