Hi Rainer,

That's quite interesting, there's even a 500K gate (Spartan-3E I believe) part.  A tad
expensive at 59 euros.

Pins haven't been a problem for me since my designs are so far all contained within
the FPGA.  A commercial product would need (at least) access to a display and have
controls.  48 pins is probably enough for that and a bit more.
