I now use a borrowed Linksys router for my main wireless network, plus an airport express for airtunes. Now that I have to give the linksys back, what should I replace it with -- another an express, an extreme, or another router (e.g. D-Link, Linksys, or whatever). I'm tempted to avoid the airport extreme (it seems unjustifiably expensive). Thinking seriously about a DLink. I love the airport for its portability (I could use a second one so my home wireless can survive while I travel, taking the one hooked up to the stereo with me). I'm especially curious about speed differentials. I'm supposed to be getting 5mbps through my DSL, although I've never seen it! Is it my router? Would speed matter if I'm using the Express as an extender anyway? Thanks.
