Gabriele,
I'm not up to speed on what's what on Ebay at the moment, but maybe some general pointers will help. Most important rule of thumb is, generally speaking, try to get older ones are they're much better finished than the newer ones.
For the block plane, look for a low angle one (see the other thread for why) preferably with an adjustable mouth to give yourself maximum flexibility. Something like a
Stanley #60 1/2 or Record #060 1/2. They're just about the most common, so you shouldn't have to pay
too much. Expect to have to tune it up though.
Spokeshaves? Well a metal bevel down is probably the easiest place to start and have a good chance of getting a user. People seem to like to have adjusters, so the common
Stanley 151 is often recommended. The 152 is just the same but with straight handles. Personally I prefer the plainer
Stanley 51 which should be a bit cheaper. Like the 151/152, the 52 is the same but with straight handles. If you can find one for not too high a price (doubtful) the adjustable throat
#53/54 is a nice shave. Finally, if you can find one that has a blade in reasonable condition (not too worn or pitted with rust) a wooden spokeshave is just about my favourite type, particularly on end grain.
Hope that helps a bit, and doesn't just cause confusion.
Cheers, Alf
