I was in the club for 10 years. Bought a Komatsu 1992 PC220 LC that really had nothing wrong with it. The boom cylinders barely weeping bugged me so I rebuilt them. Had to replace a few hoses. They are tons of fun for a while and then they turn into work. 40 grand went a long way on my new tractor but there are many days I miss that big machine.
A mini is great and easy to move, but a bigger machine works circles around it. Your rig is a really nice size. It big enough to do real work and not obnoxiously huge. My father had a Komatsu PC150 that was the bee's knees!
