CT2K, CTSW are probably the best value second hand at the moment if you want speed, but check the empty weight, and favour one that's been hangared.
Nothing wrong with the banbi, but buy a British one. Importing from France is likely to just create a world of troubles to solve when all you want to do is fly.
Slower, but not that much slower, look at the C42 and Eurostar. They are also extremely robust, which might suit a new pilot well.
Also look at the Microlight version Jabirus.
The Dynamic is gorgeous, but very expensive and perhaps a bit of a handful for a new pilot.
I can't think of anything fast with wing fold, but if the second feature is more important, look at the Escapade, which is very nice, very well supported, and has an excellent wing fold mechanism. But no, it's not all that fast.
