We use the Superfos vapor lock 502 for everything now.  I buy a case every year or so but we wash them and reuse.  Cost is pretty low at higher qty and as high as a buck per or so by the 100pcs, for both container and lid. 
Are those delitainers you linked to really airtight and durable to drill mix in?  I would expect a result like mimosa had but if they were higher grade I could see it working out.
