I can't guarantee they're the same, but I've seen a lot of vendors sell these power supplies, and the pictures hint that they're the same units. For example, Sure Electronics sells this 12v, 29A for $26. http://www.sureelectronics.net/goods.php?id=1707
Kysan makes really solid stuff, so I would trust anything they sell. In fact, the miniature gear motors that Solarbotics, Pololu, etc. sell for $20 each come from Kysan for about $3 each per 1,000. The only downside is that they have a $100 minimum order. Last time I ordered from them, it came in 3 days. From China.
