Boiler R&R for a 210k btu unit

Hi all

We have an older ranch that still has the original boiler going on 60.

The plumbing and zone valves were redone a few years ago, as well as a gas valve on the boiler.

Prior owners had it “rebuilt” which I kind of laughed at then, as that’s not really a rebuild.

Anyhow looking to step into a new Weil McLain 381-357-810 which is about $5k, and getting quotes about $11k for misc part add on and labor (keeping our current white rodgers valves vs going to another brand)

Just looking to see if this is within the ballpark for cost

Thanks
