We get slightly different configurations down here and to complicate things even more a lot of them are rebranded.
As with the others, a used commercial is the way to go but pay close attention to the exterior condition.
A lot of commercial uses leave their mowers on their trailers out in the weather and I find that these people have a different attitude to maintenance and their mowers.
Also have a good look at auctions from your civic authorities.
Any mower sold by them is generally in good condition because most service them by the book to the letter.
Down here they go cheap because they have massive hours on them
There is a lot of truth to what you say, I found both of the used mowers I bought through homeowners who at the time bought a commercially-rated model (and I say that because to me a 10-gauge deck doesn't warrant a commercial grade yet Dixie Chopper calls it commercial), but to find a gem in the haystack is a trick indeed. Not many homeowners out there will buy a commercial grade machine, and the few who do either keep it forever or when they sell it's highly sought after.
But you do find them, the secret is there is no secret, mostly it takes time and effort as I have found no matter how I cut it, I pay for the machine one way or another. A friend of mine used to describe it thusly: Once I have my money saved up I look in the classifieds every day, and I mean every single day.
I could not agree more, you have to have the money, cash, all of it. Then you start looking, and keep looking...
Because you have to educate yourself, reading articles / discussions such as these might come in handy...
It is rare you will find a good deal right off but even if you do, how will you know it's a good deal?
Just for example, did anyone catch that bit about 7-gauge vs 10-gauge steel?
Knowing details like these, what it means...
There is no one thing that separates good machines from bad, rather there are between several to many key factors that do, almost like with a car.
Then there are those machines that are a good deal but they need some work and sometimes that can run into the $100's just in parts...
Might not be so bad if the selling price is right, but do you know how to do it because paying someone else could get costly.
You have to educate yourself, one such way is start looking and keep looking.
So much so that by the time it's all said and done I find I've either invested quite a bit of my time and effort into getting a good deal...
Or I ran to the dealer and paid them the big money and done.
Either way I paid for it.
One other thing to consider, some dealers might have a 'demo' model or two they'd be willing to sell.
Demo models are machines the dealers allow potential buyers to test-drive, most are still really close to new.
