Hello , I am beginner and I need an advice  on buying my first practice amp.

My list is (All around 150 euros , except Cube 30x):
1. Roland micro cube gx
2. Fender mustang 1 v2
3. Orange cr35ldx
4. Blackstar ID:Core 40 v1
5. Line 6 Spider classic 15
6. Second hand Roland Cube 30x
I've always liked the Cubes. Also, definitely buy second hand. You'll get much more value for your money and be thankful in the long term. There's nothing more discouraging than a bad amp.
Roland Cube was my first amp. Nice little compact tones. Don't get a Line 6 spider! I don't know why these things sell so damn much - they're horrible sounding.
You're much better off getting a Fender or an Orange. And I'm not saying this just because I'm afraid of spiders...these amps sound crap.
