The "DKB Cash" account will also earn you 5000 award miles on M&M if you are so inclined to collect them (and another 5000 for someone referring you).

However, if you plan to use the account only for use in germany, I'd recommend you open an account with a german savings bank (Sparkasse resp. BW Bank in Baden-Württemberg) as there are no fees associated with buying something using the Maestro card and cash withdrawals are free at most Sparkasse ATMs throughout germany (and almost every little village has its own Sparkasse). However, I'm not sure whether they'll let you open an account unless you have an address in germany. The downside: They'll charge a fee when you transfer money from a foreign account (when customers from switzerland pay my bills, this always draws a 5 EUR charge for a SEPA transaction).
