that is great that you have PE Paul, there is a lot of help out there for it, Techno babe https://www.facebook.com/technobabeinc/ does some great PE videos.
I love having my big hoops on my PR as well, but I am amazed at the size of some of the new home table machines (the ones that look like a normal sewing machine)
The key to the PR's is the daily hook oiling, they are a great workhorse. be prepared for a shock at the servicing costs, each of the little felt pads and there are 2 per tension dial are over £5 !! make sure you cost in the maintenance with your prices.
you will be hooked, I sat and watched mine for hours when I first had it, it is like watching magic just appear.
