I got a 4 year old KA6 last summer for $2000.00. I'm sure that boiler is fine but the price is a bit high for how old it is. Doesn't have the combustion air blower, either

I believe that boiler is a late 80's model. Looks sound but it is over 20 yrs old.

It looks like a very nice boiler. It would benifit from adding the extra combustion blower that comes on the later Keystokers. The extra combustion blower runs 24/7 to give a more complet burn. Keystoker sells this as an add on kit for older models.
It's been flushed, pressure tested, cleaned, painted and re-gasketed, if you can trust the seller, it looks like a good deal.
One of the advantages of the Keystoker is they are still in buisiness, you can call them if you need a part. Also they make stokers and boilers that last a very long time with little problem.

Hopper lid doesn't look like it seals very good , is that a non-issue for this unit ??

There is no hopper lid. Not required for whatever reason. I've run mine to pretty near empty many times and no problems with a hopper fire. I was at home when I let the coal level drop just to test if the fire would move into the hopper. It hasn't. I keep the hopper pretty much full all the time now.

Carbon12,you are right,there is no hopper cover :oops: looked at it again & sure enough !! Well,i am still learning,but i thought all stokers had lids to keep CO from backing up thru the hopper ??

I know many stoker stoves have them. As far as I know, none of the keystoker boilers or furnaces have hopper lids. My digital CO meters in the boiler room have never logged any CO. I have 2 digital read out meters and a regular CO alarm in the boiler room. Nada so far, thank goodness

That looks like a very nice boiler. The weak point in the pressure vessel is the area around the tankless coil. Many of them leak and corrode the boiler...but this one appears to be in very nice shape. The only thing I would do that they haven't already listed is install a new motor on the stoker...but that is just my preference.

A new KA-6 is $5000-$6000 depending on the dealer. I wouldn't hesitate to buy a used one and pay for the installation with the difference.

The youngest EFM in my family is 22 yrs old.

I never buy any equipment of any kind that has had the "aerosol overhaul". It covers up information about how the thing has been maintained over its lifetime , I can do my own painting , thank you very much. I wanna see new parts not new paint!

I would venture to say that if the sheet metal were in need of a re-paint, it was not to cover up anything. I repaint every single one that leaves here. I do understand your concern, however if before and after pics are included, that is fine by me. Axeman-Anderson never used to paint anything, and you got 2 cans of Aluminum paint. DONE. Now some 60 years later, they do come painted.
The point being that a pressure relief valve that dripped for 30 years makes things look horrible, but functionally, they are just fine. The 'Bug Bomb' tune-up is NOT a rehab, however if the proper steps were/are taken, then there is no issue IMO. Witness the AA 260 that Keving did in Maine, or the fine Yellow Flame that Don has just brought back form the dead.
I do know something about this K-6 and the seller does very good work and is not in it to get rich. I have 2 machines running that came from his stable, and I had to do nothing to either one. Been a few years and only cleaning and lubrication. Most of the time you get what you pay for, and this is one of those cases.

2001 Sierra,my apology for not reading the whole title to this thread,i got excited with "used" & disengaged my brain & then put my non-experienced thoughts into words,of course if i hadn't i wouldn't yet know that some stokers have no hopper cover,constantly learning !!
