I'd avoid that telescope because of the mount.
It's not likely to be stable or easy to aim precisely. This means it will be frustrating to use.
As magnification goes up, so does the need for a stable mount. You might not notice it vibrate in the breeze or while you're focusing if you look at the telescope, but when you're looking through it the vibrations will be magnified just as much as what you're looking at.
Most people who buy a scope like the one you're looking at will give up on astronomy or buy a better telescope before they've seen five objects they can identify with it.
The least expensive type of telescope mount that's stable is a Dobsonian.
A good basic Newtonian on a Dobsonian mount starts at about $180 in the USA, and with a 114mm diameter mirror, it'll gather 2.26 times as much light. Here's a link to one at a dealer in Germany.

It is about twice as expensive as what you're looking at, but I've known people who have had that scope and enjoyed it for years. You might find a better deal elsewhere - I'm not familiar with European dealers.
Otherwise, the best thing you can do while saving up to buy your own telescope is find and join a local astronomy club. You'll be able to observe with people who have more experience than you, and they'll be happy to have you look through their telescopes. Membership is usually very inexpensive.
Good luck.
