Alas, I've found no ready-made boilers in the "more than Midwest, but less than National Debt" cost bracket. I think that's because it's easier to learn how to machine metal (and make an engine), than to learn how to build a pressure vessel. Plus, CNC can cut metal precisely, but there is no CNC-equivalant for boilers. Graham engines (well recommended) are CNC, I believe.

If you are new to steam, I'd recommend the Midwest Heritage setup - I see 10 min runs for a 2' paddlewheel hull, and 20 min runs for a 4' prop freighter. Adding complexity to motor performance (reverse, self-starting, throttle) or to boiler (feedwater, whistles, gauges, sightglass) considerably increases the System cost.

A fancier engine requires a fancier boiler. It's sort of like replacing a brushed motor with a brushless - more expensive motor requires a more sophisticated ESC and bigger batteries. Model steam does not have the number of modelers as electric planes, so we don't get to spread the factory costs over more customers.

I'm going to build my next boiler. I can understand the price of an engine but not the prices of boilers

You just need to learn the art of silver soldering and annealing copper sheet and tube. I would suggest calling the local plumbing, rain gutter and sheet metal shops and beg for some scraps of copper remnants. Tell them you are building a scale model steam engine and boiler and they may help you out. They like to know that you are making something completely out of their realm and not threatening to their profit making.
You can even build your boiler shell completely out of rolled copper sheet.

Good for you that's what I like to hear, you give it a go and keep posting your progress.
Be prepared for the price of copper and sliver solder, it may give you a shock at the cost of materials to build your own boiler.

Yeah this is true but luckily I bought a 8 foot pipe 4" in diameter about 3 years ago for $30 and a bunch of silver solder as well so I hope I can build a boiler for less than $600 USD

Great score on the copper tube!
Would you be interested in selling 12" of that to me?
Kind regards,
Giovanni

Hey, you are one lucky Dude
In the U.K. we can only buy copper tube from model engineers suppliers and a 12" length of 4" dia x 16 swg ( 1/16" thk ) tube would cost you 32.
I wouldn't advertise the fact that I had as much or you will have everybody and their uncle wanting a piece.
George.

P.S. I see that they are already there.
