I'm still just staggered that there isn't really a cheap, 8-port consumer 2.5G switch in the $50- range yet. Consumers have been stuck on Gigabit for about 20 years now and with 10G being extremely common in the prosumer and enterprise world for well over a decade.
It's still new, so everyone's trying to make a bit of extra cash on it.
At least there are eight port switches from multiple companies and the five port ones will soon be $100 a pop.
$20 a port is still a bit steep, but I bet in a year or so, that'll be down to $10 a port.
My now "old" GS110EMX hasn't really dropped in price ($249 MSRP) over the almost five years it's been in the market. Looking at CamelCamelCamel, it seems to have been sold at less than $180 during a very brief period of time, but that's where a product like it ought be priced after such a long time in the market.
In all fairness, I don't think it's a volume product for Netgear, but so far it and the non managed version have been the cheapest, fanless 10Gbps switches out there.
Trendnet has this, which is quite interesting, but at $400+ and no copper 10Gbps ports, it's a bit steep, but it's the kind of switch I'd want longer term. At least it has dropped over $170 on Amazon since it launched and it's apparently been sold for as little as $329. It's not fanless though... It's also not compatible with 10Mbps Ethernet

A couple of years ago, Realtek was showing off a cheap 10Gbps five port switch, minus PHY's that was going to sell for around $20, but I'm not sure what happened to that.
