You might also want to try NGC (also on Kiwi's website - http://www.oldgamemags.com/consoles/nintendo/ngc/) by the same people as PGB. It's mostly dedicated to Gamecube, but for the first few issues (60-67) they had a section dedicated to GBC and GBA, and also from 102 onwards, covering DS and GBA. The rest of the issues cover GBA and DS games within the regular reviews.
