ASR1001 would be my recommendation or there is a "service module" for the
Cat 3560X switch that adds netflow capability.

ASR1001 MSRP $17k + $5k for IP BASE licence

WS-C3560X-24T-S MSRP $4,300 + $3,750 for C3KX-SM-10G service module + $500
for dual PSU

neither of these options is close to the €3k target, and neither is readily
available used.

Up until recently Cisco had few low-end router platforms that could shift
1Gbps - only the 7304 NSE-150 or 7200 NPE-G2.  Both are available used -
I'd recommend the G2 above the NSE.

The Cat switches can move the packets but support for IPv6 and Netflow are
limited.  I don't know how software in Nexus is shaping up.
Other than that you're looking at high-end routers like OSR (10k), GSR
(12k) or CRS which are overkill for the requirements.

If you're looking for a non-Cisco solution, how about a Mikrotik?
According to them the RB1100AHx2 can do >1Gbps and nearly 1Mbpps for less
than €500, which is cheap enough to try one to see if it meets your needs -
