That's the same boiler I have, it's a very good boiler. If money is an issue, I would do the acid wash and consider a water test/ softener. If money is not an issue, I would go with a superstor. You could also replace the tankless coil, the cost is $350 to $550 for a coil depending on the size, so the price you got isn't that far off, it's not a difficult job, drain the boiler, cut 2 pipes, unbolt the coil ( mine had stainless bolts), install new coil and gasket, solder pipes, fill boiler. You may want to get another quote to keep Eastern honest. I assume the guy you used made sure the mixing valve isn't the issue. Good luck.
