dataflame - 7eur month ($9), 2gb, 6gb transfer
It's $9 a month for 1gb and 25gb transfer. Not sure where you got that info from?
As for powweb - if you fill up the 300gb of space and use 3000gb transfer in one month they'll cut you off. In fact you'll get cut off a lot sooner before you reach that limit - No way in hell can you genuinely use that much for only $6
