I had to scrap an old Cehisa bander, I had bought used. In my case this was a machine from the late 80's, and while it was built very well. It just wasn't designed for what I intended to use it for, nor was it up to modern standards. I am sure the machine you are looking at, is far better, so the details of the particular machine I bought, don't apply to your situation.
However. I learned some other things that do in the process.
1. Pretty much one supplier for parts, tech support, etc...
2. Parts are going to be expensive. One supplier, means you are not getting this stuff elsewhere, unless you get really creative.
Use this to negotiate the price down. Find out every wear/consumable item that may need to be replaced. Call, the dealer, and get a quote for these parts, and see how many they have in stock.
3. Make sure the machine is going to come with the complete factory manual. Otherwise. Call, the dealer, and get a quote, for a replacement manual. You will need to do this, before you can call tech support, and the manual may not be as cheap as you think.
4. Tech support won't be free. You will be paying by the minute. See if you can get the prior owner to train you, in operation, and setup. Get as much knowledge from them as possible. This will save you some serious time, and money.
5. Find an independent supplier for glue. This will save you a lot of money.
6. See if you can find an independent supplier, for the waxy/rubbery stuff they sell you to clean the glue pot. Even better if the machine comes with some of this. It costs a small fortune from the dealer.
