Electric models don't reach the same pressure as stovetop models, so recipe cook times won't be right.

In your price range the Kuhn Rikon is a really good piece of kit.

The best brand I'm aware of is Kuhn Rikon.

Considering they're made in Switzerland, it's bizarre they're cheaper in the US (£178.39 against $159.96, though it is on offer in the US)

However, how will you get it back? Airport security might not like a pressure cooker, plus you might end up paying duty.
