Extreme (ex Brocade) SLX9540 will do full tables from a couple providers
in a local edge scenario with their "OptiScale" FIB optimization/route
caching, but the whole FIB won't fit in hardware.  Bandwidth is very
generous (up to 48x10G + 6x100G), and prices are reasonable.  You
wouldn't need any of the stupid port licenses, just the advanced feature
license, so it should be about 25-40% more than an MX204 based on public
pricing I've seen.  That would get you 24x10G + 24x1G (the rest of the
hardware is all there just locked out).

The SLX9650 will supposedly (if marketing and my SEs are to believed) do
4M IPv4 in hardware FIB, less if you want IPv6, too but still full
tables of both with ample room for L2 MACs, next-hops, and MPLS.
Bandwidth is, well, "Extreme" at I think 24x25G + 12x100G (25G breakout
capable, all 25G also capable of 1G/10G).  Pricing is supposedly "about
double" a 9540.

Be advised that the control plane SOFTWARE is NOT as mature as JunOS.
It's being built up rapidly, but there's still a lot of stuff missing.
I have not, so far, run into any of the weird glitches that I've seen on
older Foundry/Brocade products, though, so that's good.  There's also no
oddball restrictions about port provisioning like the MX204 has.
Control plane HARDWARE is well more than capable with something like
16GB (or maybe 32?) of RAM and a Xeon CPU.  There's actually a fully
supported option for a guest VM for local analytics, SDN, etc. in remote
scenarios.

If you just want to push packets, they're nice boxes.  If you want "high
touch" service provider features, I think you may find them lacking.
They're worth looking at, though, if only because of the
price/performance ratio.

Arista has some similar boxes with similar caveats in terms of infantile
software.

MX204 is a very nice pizza box router for service providers.  I'm not
aware of anything quite like it in terms of having a mature control
plane.  I like the JunOS config language better than Cisco-style that
most other folks use.
