The sales rep recommended the MX 104 to us first, but then came back to us and said "Sorry this router isn't adequate for your needs you need to be in the MX240 Chassis" I read the spec's I can find and it says from a routing engine perspective (RE-S-MX104)  that it will handle the routes with room to grow on."

I am hoping to find someone here who has tried this config and will either say yes this is great solution or  OMG, I'd never try that again.

The MX104 will support 4x BGP sessions in the control plane (4GB RAM).
The problem is that the CPU on this router is massively slow, so you
will be in pain if you've got lots of churn.

FIB-wise, you will be fine with the MX104.

If you have the cash, go for the Intel-based RE's (MX240/480/960). If
you don't mind Cisco, consider the ASR1000-X platforms.
