Tunze 6100 with Tunze Magnet $150

Just one Tunze 6100 left...
I have two Tunze Stream 6100 controllable powerheads including all cables, magnets and an AC3 AquaSurf module for sale.  I would like $400 for the entire package.  Below are the specifications:

A couple of things about the pump that I should mention - the magnet mount is a little loose on both pumps.  This is a common problem and can be resolved by either gluing the mount in place or using a zip tie; both inexpensive, reliable and easy fixes.  The pump impeller is missing an anti-reverse tooth (the tooth on the impeller that extends if the pump attempts to start in reverse).  The screens on the pumps have been modded to increase the flow by removing every other fin.  I've not used the pumps myself, but I saw them in use when I purchased my current tank. 
Manual for Tunze Stream 6100 Pumps
Manual for AquaSurf
The Tunze pumps are not the current generation, however, they are great pumps, extremely reliable, and you can still acquire spare parts for them.
The pictures below show more items than this listing includes.  You will get one Tunze 6100 pump w/ magnet, transformer and driver for $150
Entire package $400.

I never used the Aquasurf so I'm the wrong person to ask about that.  When I set things up, I went straight to Vortechs...I've had these laying around for a year and it's time to move them.
Anyone familiar with the Aquasurf that can give Jim your opinion on them?

There's a guy on RC interested in the pumps, but not the Aquasurf. If he's interested in that, would you be interested in the AquaSurf at $75? They are $175 new for the module, then the cable is an extra $20.
