Do yourself a favor and get a Blackberry Playbook. Hands down it is the best hardware you can get for the price. It's portable (i take mine EVERYWHERE) has a beautiful screen, great for multitasking, the Print2Go feature is very useful for school, and its cheap. $199 for the 16 GB if i recall correctly.

I wouldnt recommend a cheap Chinese tablet, cuz you'll probably regret it at the end of the day. besides for 140 euros, you mite as well for the the playbook (i dunno what the euro conversion is, but its probably not far off)

When you're looking at cheaper tablets, you really only have a few choices...Playbook, Kindle Fire, HP TouchPad (good luck finding that) or a few other comparable Android tabs. I dont think there are many that are in the lower price bracket, and i can say for sure the PB beats out any tablet in its price range in terms of hardware specs. Plus if you're using a blackberry, you can bridge your data plan, so you have internet anywhere you go (you can also hotspot, but some carriers charge for that while bridging is always free)
