The components inside a SV cooker are dead simple and it's very easy to make them reliable enough to not matter. The Anova isn't a toy at all, even at $120, reliability has been very good and many people report running them hours per day over multiple years. Even if an Anova only lasts 3 years and a Polyscience lasts 10, by the time the Anova dies, you can pick up the next gen model for half the price and still save money. The only big tricky issue with SV is dealing with humidity and electronics but that's fairly simply fixed just by making the electronics low power enough to be passively cooled and completely sealing them as the Joule has done.
