We use the RC 2000, which also is sold for the price quoted of $210. This is the one you will want if you want to surpass what the Porty is capable of. The picture initially showed is the RC 1000. And though it is better than the large Porty, it is still in the same category with a 2.5" barrel and a 2205 lb working load.
The RC 2000 doesn't sound that much bigger with a 3" barrel but it is really stout. It has a working load limit of 4410 lbs. That is right up there with the big boys.
These are cool devices that really do bridge the gap between the Port-a-Wrap and a strap on bollard. I like them a lot. They are stable enough to make taking the rope on and off very easy, yet the fact that they still pivot gives you more options in work positioning. I can't even imagine breaking one of these things.
If there is a down side to the RC 2000, it is only that along with its capacity for handling far larger wood than a Porty is the fact that is where it shines. Meaning for small, light pieces, you are going to need to go with a lighter weight line to get it to run smoothly.
This is not saying that it doesn't handle light wood well, you just will not really notice its advantages until you start getting up to the bigger stuff. And for a unit of this size, it is really quite amazing.
