You were surprised by the extra fees. You had no idea if the supplier would help when problems occurred hinting that u did not do due diligence. You have no idea if you can get spare parts. You did not check that all nuts were tight. You should have bought one machine at a time to test the supplier. When you get cataract surgery, you get one eye done at a time. Most people don't do proper due diligence but you openly admitted it. Seemed like you paid too much to supplier for machines. Maybe the supplier has better quality/reputation than the suppliers charging less.
On the other hand, ianjoub actually shelled out his money, He actually has the machines, is sorting out the issues that come with all cheap chinese knock off machines, and is moving dirt.
You however, are just saying he "paid too much" blah blah blah. But he's thrown his chips on the table.
You could research forever and all the chinese sellers will extoll the virtues of their machines "just like CAT, Kubota etc- at half the price". Whatever- they are all liars, and a lot of them are here today and gone tomorrow- so I'm not sure what good a bunch of research is- half the companies you looked at two years ago may be gone.
I personally would buy older domestic production equipment vs. new chinese crap- but that's my personal hang up about the chinese. A country dedicated to the destruction of freedom gets as little of my money as possible.
But for what ianjoub wants to do- he's just working personal stuff and the time means nothing (if its down for 6 weeks- he's not out a contract)- I can see why he would buy what he did,
Buy whatever you want and tell us how it goes. Get in the ring.
