I went with the Via Aqua 1300 because it is cheap.
Don't laugh, it was my first post at PC.
You have to be careful when you assemble it.
The impeller shaft is probably two or three mm shorter than it should be.
This makes the shaft prone to jump out of its rubber bushings if it is not assembled carefully; this is especially true when it is turned on.
You can tell when the shaft has jumped because it makes a clicking sound, which is the anti-lock feature of the impeller.
The anti-lock feature is caused by the impeller impacting the walls of the pump.
But, if you assemble it correctly, it will not click at you.
