Replace a stolen Galaxy SII on a budget - options?

Hey a member of my family had her Galaxy SII stolen whilst she was out and about yesterday but cannot afford to replace it whilst she is half way through her contract. She does (as a gift) have a Nexus 7 on the way so this should give her a lot of the functionality she may be missing. Could you guys recommend a cheaper android phone that could replace the SII with? Anything really good for the cheap price aka Nexus 7ish?

Cheers
