Thinking about a switch for my rack in the datacenter - can't see any reason not to get an Aruba Instant On 1930. Only ~$300 used, still gets free updates (unlike Juniper), does PoE should I need it (Rasperry Pi hosting anyone?) and has a nice GUI for noobs like me (although I do find Junos CLI pretty easy to use). I'd prefer an EX3400 (price isn't much different) but paying for a support contract to get updates sucks
