Just buy the extract kit, and all you'll have to do is steep grains as always. That said, mini-mashing is a fun upgrade that isn't particularly difficult and doesn't require any expensive additional equipment (maybe $15 worth for a grain bag and a small 2-gallon cooler), and can help you make better beer. Do a search for mini-mash or partial mash, and you'll find plenty of threads that explain what the difference is.
