One of my biggest hobbies is lifting weights and its a great passion of mine. After I graduated college I no longer wanted to make the drive out there just to attend the gym even if the membership fee was going to alumni pricing. I decided to buy a bunch of gym equipment and put it in a buddies garage who lives 5 minutes away. We've probably spent around 5000 dollars all together (split between a few guys) for a power rack, 600 lbs of weights, prowler, two power bars, three specialty bars, weighted vest, collars and all sorts of other knick nacks. It really fills every possible need I could ever have in terms of training and I don't regret a single dollar I've put into it. I have the freedom to play whatever music I want, talk as loud as I want, and do whatever I want. It'll pay itself off over time, not to mention its massively convenient.
Aside from that, I do have a japanese chefs knife that i purchased which I cherish. Many of the hard wearing, durable clothing items I've purchased do cost a little bit more but I really appreciate it when they last. One of the worst things is having things break on you..
