I share my experience with R&S RTB 2K scope choice in Europe :
I was divided between new RiGOL MSO5K scope and a R&S RTB 2K. About technical specs (bandwith, refresh rate, memory), RiGOL was better than R&S for the same price. I mean you have a 70MHz, 2.5Gs/s, 20MPts and 50K wfms R&S scope Vs a 100MHz, 8Gs/s, 200MPts and 500K wfms RiGOL scope but RiGOL after sales dept isn't there if you need a scope (e.g. your scope is out of order and you need to not keep without one) whereas R&S has a complete European After Sales Dept who loan you a scope during time when your scope is fixing. That's a real diffrence between 2 worlds : would you like to get only a price or are you ready to pay something to get a good support to help you when you encounter a failure with your device.
As you've guessed, I've choosen the R&S solution and got a little extra from them. I've appreciated they've made a little gift
Keep a good supplier is better than get the lowest price possible.
Even if R&S was my choice, the most important is to continue to get a lot of scopes suppliers to challenge themselves
