You're quite welcome! Just between you, me, and the rest of the list, I'm British too, so replying in English isn't that tricky for me. ;)

Well for a basic, analogue implementation of FM synthesis, I gather the A-111-1 is much better than the A-110 as it has a linear FM input for just such an occasion. As the A-110 doesn't, FM synthesis using an A-110 is exponential rather than linear, which generally doesn't sound as pleasant. At least, that's what I hear people say. I need to set aside some time to experiment with FM synthesis properly. The chip the A-111-1 uses is becoming scarce though, so if you do get one of those, it'll need to be fairly soon.

For sequencing, are you talking about the simple analogue kind, or the much fancier computer controlled kind For the simple kind, check out the A-5XX range of modules over at http://www.doepfer.de/a100.htm or even the MAQ 16/3. I'm more into the 80s/90s synth era than the 60s/70s one, so I haven't really looked into these myself, but for space music type affairs, they should be pretty good!

Polyphony's a bit trickier. You can either get several of everything, or some kind of multitrack. Computers are so fast these days that you can happily record dozens of tracks over the top of each other before having to bounce them down to a single channel, so a single monosynth is enough to make some great music on if you have enough patience. (It also means you can do things like portamento up on one channel and portamento down on another at the same time, when playing chords.)

Sorry I couldn't be more helpful, I think I use my Doepfer A-100 in a different way to most people here... :)

Hope that helps,
Zoë.
