BJ's has a "PoolBlaster Catfish" model in stock for $99. It appears to be manufactured by Water Tech, manufacturer of the PoolBuster. this a cheap imitation of the Pool Buster or merely a rebranding of the original Pool Buster? It uses non-user-replacable Nickel Metal Hydride rechargable batteries.

here's a link to an online store that has it at the same price.
