I do use L3 switches for BGP at some locations (Cisco 3750) and they perform great. The problem is no instrumentation (e.g. Sflow, netflow). -mel via cell

What about L3 switches? You could receive full BGP table with Linux BOX with ExaBGP, parse it and feed to L3 switch.

I second the Mikrotik recommendation. You don’t get support like you would with Cisco but it’s a solid product.

For about $1000 you could get a Mikrotik CCR1036-8G-2S+EM but it only has 2 SFP+ ports.

How cheap is cheap and what performance numbers are you looking for?
About as cheap as you can get:
For about $3,000 you can build a Supermicro OEM system with an 8-core Xeon E5 V3 and 4-port 10G Intel SFP+ NIC with 8G of RAM running VyOS. The pro is that BGP convergence time will be good (better than a 7200 VXR), and number of tables likely won't be a concern since RAM is cheap. The con is that you're not doing things in hardware, so you'll have higher latency, and your PPS will be lower. What 8 core Xeon E5 v3 would that be? The 26xx's are hideously pricey, and for a router, you're probably better off with something like a Supermicro X10SRn fsvo "n" with a Xeon E5-1650v3. Board is typically around $300, 1650 is around $550, so total cost I'm guessing closer to $1500-$2000 that route.
The edge you get there is the higher clock on the CPU. Only six cores and only 15M cache, but 3.5GHz. The E5-2643v3 is three times the cost for very similar performance specs. Costwise, E5 single socket is the way to go unless you *need* more.
