I think you can only get the cranesmart from the factory in canada. I always talk with Howard.
Just because the military uses trimble, just means they were the lowest bidder, not that its the best thing out there. Helps that they are us made, for getting the mil contract. Not likely to source from canada for that.
I've had issues with LSI, batteries don't last, screens go bad. And when the screens go bad (On 2 of the 3 systems I had had screens go out), from the factory- "no, we can't sell you a screen because that model is 5 years old- we don't support it anymore, but you can buy a whole new system". If you won't support what you made before- why would I buy a new one from you? So cranesmart for me.
The screen on the cranesmart is easier to read, the load cell doesn't have a little antenna sticking out of it that gets damaged. Batteries last longer. Its just a more robust system.
And yes, the $5,000 is a lot of money, welcome to the expenses of crane equipment. You really aren't buying the system, as much as you are buying their liability insurance.
I'll look and see what they call the model I have, I would find out first what exactly your new rig has, and what of it works, before I went and bought a lot of extra's you maybe don't need. If your A2B works fine, no need to add the cranesmart a2b, same with boom length and angle indicator. Don't replace what already works.
