I found a set of loegering tracks and spacers. They are used but the pins aren't worn much and they look to be in really good shape. The guy wants 1000 for them. Is that a good price? Is there anything I should look for before I buy? The other question is are these hard on a machine? I've seen them on lots of machines but just never run tracks on a machine. My machine is a 2000 873G and I use it on our farm if that makes a difference. Thanks for the advice in advance
