Sometimes reading junk mail pays off. I just found a small dorm fridge for $40! I like to keep my insect larvae/pupae in a small fridge that I can keep warmer than the "real" fridge so things don't get as chilled (houseflies, waxworms, eggs, etc). This is the cheapest I've found yet, so I thought I'd pass it on. SierraTradingPost.com has a Vector Travel/Dorm Mini Fridge plus a couple of other types of coolers for under $50. Item # 98244.
