200e

The combination of this two is great.
I have the smaller 3-boat panel system, which are the same width as a 
Serge panel (sans rack ears) and the only thing I had to do to 
optimize compatibility was to add some voltage to my TKB's gates (they 
are 5V, and the 281e needs 12V). I do this by feeding some 255e 
voltage into the 210e and mixing the TKB gates in.
As for the make up of your proposed system: do you really like the 
259e? The aliasing is, frankly, too much for me (but I guess it's a 
matter of personal preference). That's why I have a 261e on order. 
As for the exchange for a bigger system: talk to Don.
I think he might be willing to do some kind of exchange (as long as 
they are still within warranty, maybe?).
