We use both the MX240 and MX480 (for 100G) 1800REs.  Very happy with this hardware.

I am needing a device that has a mix of layer 2 and 3 features, including MPLS, that will have a very low port count requirement that will primarily be used at a remote POP site to connect to the local IX as well as one or two full route transit providers.  The MX104 has what I need from a physical standpoint and a data plane standpoint, as well as power consumption figures.  My only concern is whether the REs have enough horsepower to churn through the convergence calculations at a rate that operators in this situation would find acceptable.  I realize that 'acceptable' is a moving target so I would happily accept feedback from people using them as to how long it takes and their happiness with the product.
