I do the same thing, I'm always looking around for the next best thing. I have little glass desert bowls with lids, I think they're pyrex, not sure, Have to check. anyway, the beauty is, you can seal them up for storage. Got them in the kitchen/housewares section of wally world or Target'..The bad part is waiting for the puck to adhere to the glass. The first two times, it sloshes around in there, and keeps spinning like a record....
