I'm trying to decide between buying an Airport Express and coupling it to an ADSL modem, versus buying an all-in-one modem/router unit. The latter can be bought these days for not much more than $100 but I'm a bit nervous about it as I've found that home Wifi networks with sub-standard equipment can be temprimental, particularly if you want to use some of the more advanced features in iTunes.
Is there any substantial benefit of an Airport Express over a cheaper third party solution? Any thoughts or advice would be appreciated.
