If there was a WRT54G version with Gigabit ethernet, it would be my daily driver today. Having a 100mbit/sec switch is the only reason why my WRT54G is sitting in the shelve without any work. I only use it for tinkering one day or the other.
Alternately get an Edgerouter X and install openwrt on that.
So yeah.
Even at MSRP (280), the 3200 is cheaper than the 54G was at release.
I had to look because I was wondering "Do they really charge $1000 for a consumer router + AP?" The answer is no.
$250 vs the $200 of the WRT54G in its heyday doesn't seem so bad for 15 years of inflation
GL versions were 20€ more expensive, usually.
EDIT: apparently it dropped in price considerably in the first few years.
Here it is on Amazon: https://smile.amazon.com/gp/product/B01JOXW3YE/
