I use that same router and it works fabulously. Of course the AEBS is going to be easier to set up in true Apple fashion, but it is not difficult at all to get that router up and running quickly.
The main difference between a standard router and the AEBS is that the AEBS has USB port that can be used as a print server or as a port to plug in a USB hard drive for backing up over a network. Of course it is a Draft-N router as well while the Netgear WGRE614 is standard 802.11G. All that means is that for file transfers over the network the AEBS will be faster if all wireless devices are using similar Draft-N equipment. The "N" will do nothing for the speed of your internet.
I have no need for a print server and have other computers on the network to back up to if needed. I bought my Netgear router for about $30 and have been very pleased with it.
