Very few people buy level 1 chargers, most buy level 2, so it may be hard to get recommendations. However many companies make both level 1 and level 2 chargers so what you can do is read people's comments about their level 2 chargers in forums like this or in Amazon reviews for example, and those reviews would give you a general idea about the quality of chargers the company makes. Also some companies make level 2 chargers that come with an adapter for level 1 so they can be used for both.
