I am getting failed attempts using the default gas limit 21000 when trying to buy DRP using ETH from myetherwallet.com
"Warning! Error encountered during contract execution [Out of gas] "

there is no mention of gas limit required on the site.
anyone else had this problem and sorted it?

EDIT:
I found this article, and did not know we need to set gas limit higher than default 21000 for ICO's
https://www.easyeth.com/participating-in-ico-with-myetherwallet.html

anyway can a dev please advise what gas limit we should be setting to buy DRP, every time I try it is costing me the tx fee if it fails, so would prefer a response before trying again, thanks.
