The MX204 seems to be amazing value for money if it has the right port combination for your workload (i.e. not great if you need lots of 1GE). The RE is also significantly more capable than the somewhat underpowered one in the MX104.
I would be extremely hesitant about deploying a new MX104 today given the poor CPU and relatively small amount of RAM on the RE. The RE CPU is also a PowerPC, which seems to be a bit of a dead end for Junos with new development work seemingly focussing on x86 (last time I looked, the MX104 is stuck on FreeBSD 6 and so has no SMP support despite having a dual core CPU for example). We ended up going with the Cisco ASR 9001 instead of MX104 due to the poor performance when converging multiple full BGP tables thanks to the underpowered RE CPU and interesting design choices in rpd. We’re very happy with our ASR 9001 (although IOS XR isn’t as nice to use as Junos), but if the MX204 had been available at the time, then we would quite likely have ended up using them instead. There is an ASR 9901 “coming soon”, which might also be worth a look at for new deployments. For our use case (border router terminating peering/transit), having dual RE isn’t particularly important as we achieve our redundancy using separate routers. YMMV.

Maybe we should look at the MX204 instead? Although, it's 2X the cost (MSRP) and only has one RE. Thoughts?

Not sure if the "locking" is actually enforced or not on the other two. Supposedly, the overall throughput of the chassis is also limited to 20Gbps - again, not sure if this is enforced. Options for 10Gbps include purchasing a single MIC-3D-2XGE-XFP and installing it in the one open MIC slot providing two 10Gbps interfaces or purchasing MX104-MX40-40G-UPG to open two of the four built-in interfaces while also bumping overall capacity of the chassis to 40Gbps. The S-MX104-UPG-* licenses to activate the 4X10GE fixed interfaces don't appear to be usable on the MX104 bundle packages (like the MX104-MX5-AC).

Can I install another MIC (say the MIC-3D-2XGE-XFP) in an additional slot to gain 2 10Gbps interfaces without purchasing any additional licensing? If I do this, is overall throughput of the chassis still locked to 20Gbps (due to the original bundle)? I can't find anything (ie "show system license") that states there is an overall capacity restriction, but I'm hearing mixed things from various sources.
