Stickleback - that looks like my boiler...
Due to upgradeitis my machine will be on the market shortly. If all else fails, you might get a an old repaired boiler out of mine. Not a scrap of scale in it.
I was thinking mine would go on the market for around $400 ono - that is the $200 I paid for it, the $450 I spent on new parts when I restored it, and the $100 for a recent new element (about 1 month old). Less 4 years of depreciation.
So I think you could bear in mind that you have this option upcoming as a back stop.
