I've one messed with the Romeo in a LGS. Seems to be well-made but I'm pretty sure it has a looooong way to go before it earns the reputation of an RMR. There's a reason Trijicon gets the premium prices for it's products, and mostly that's the reputation for toughness and reliability.
I don't have extensive experience with the Romeo 1 in and of itself, but as a range type optic I do not think you would be disappointed. If you were planning on using the gun at any point for carry, you need to spend the money on an RMR. The battery life alone makes this necessary.
