The Arista 7280R can do 40G (I think 100G) too and is "reasonable" for that speed. I've seen quotes floating around for about $20-30k. It can hold full tables as well.
Alternatively you could look at an older Juniper SRX5400, update with the latest routing engine and toss in 40G line cards. You can route 40G full duplex with ease, even VPN at those speeds. Used you're looking maybe $10k?
Unless you need to terminate VPN's or take full tables you can probably get away with an L3 switch.
