Between jacuzzi panther or berkeley? BERKELEY is the way to go hands down.

my panther is reliable... it does an honest low 60's but thats about it.  i was lucky to find one that had a new suction housing machined into the tail end. 

that being said, stay away from them.  parts are hard to come by since no one really marks parts anymore and berks are just more friendly.

Berkeley, older Dominator & American Turbine, Aggressor and Legend jets all are very similar in design and can share many interchangable parts, Jacuzzi YJ jets and Panthers are axial flow jets and work very well for what they were designed to do, Jacuzzi Wjs are built similarly to Berkeley style jets , All these jets are dependable/reliable when maintained and cared for Some are more expensive to repair when damaged (Jacuzzi YJ and Panther) mainly due to diminishing parts avaialbility and thus greater cost.  The First five jets (mixed flow) I mentioned all tend to lend themselves to high performance applications and have been the "weapon" of choice for years among the performance crowd  Tom
