Obviously, lots of people buy stuff from them all the time, or they would not stay in business.
But they tend to mainly sell to companies that want convenience, and are willing to pay more for it.
You can always find better prices, if you have lots of time, by searching for individual sellers.
Some companies are better than others.
The kinds of times when it makes sense to buy from a big dealer like this is when you need a specific machine, NOW, and are willing to pay more for getting it.
For instance, close to 20 years ago, I had a job where I had a deadline, and I needed a 48" x 12 gage finger brake by the end of the month. Where I live, they come up used maybe once a year, if you are lucky, so I bought a used Chicago D&K, sight unseen, from a dealer in Houston, and had it shipped. I am still using it daily, all these years later, and dont regret for a minute that, if I had spent a lot of time looking over a period of six months or so, I could have saved a few hundred bucks. It paid for itself in a month on that job.
But when you order from Yoder, or Sterling, you will be paying top dollar.
Sterling, I know, finances locally- and thats a big selling point in So-Cal, where there are fewer and fewer used tools, and the manufacturing economy is booming, so there is a lot of demand. The same way people lard on an extra 20 grand in finance and interest on a $40,000 pickup, they do for press brakes and lathes from Sterling.
On a big purchase, you are probably going to want to fly over and inspect in person anyway.
