Re: And.... Yep, because 5GHz equipment on the AP side is still expensive, and has shorter range.
No it's not. The TP-Link TL-WDR3500 is a simultaneous dual-band router (so it can do 2.4 and 5 at the same time), and costs $50 at retail... I'm sure there are cheaper examples too.
To put this in context, my WRT54GL cost more than that.

AC only runs in the 5ghz band... a lot of AC routers also support 2.4ghz N. However, it remains to be seen how much AC catches on.

Where is it sold, retail? Remember that the great unwashed masses don't all shop on Newegg, or shop for routers on Amazon.
Good routers are a lot more than $50 nowadays, like the ASUS RT-N66U Dark Knight with N900.
