As long as your riding conditions don't require a $2000 fork to survive it, you'll be fine with the $200 fork. But don't cheap out too much, a $50 fork on the bike is useless off road.
If you ride like Mad Rhino, you need the pricy components. If you ride like me, middle range stuff is fine. It just depends on if you ride, or if you RIDE. But when I do get to ride the good stuff, I definitely notice a huge improvement and appreciate it. I can ride longer before it beats me to death, and in general, take the same trail faster.
If you can afford the good stuff, get it, even if you don't RIDE. If you can't afford, then enjoy what you can. It just comes down to fun budget, how big is it. When I was flying, my fun budget was about $250 a week. I had the money at the time, and it was SO fun I just did not care what the cost was. Now my fun budget is more like 20 bucks a week. I still have fun, but do not have a hot air balloon around costing me a fortune anymore. I just enjoyed flying for a decade because I could afford it at the time.
If now is your time, don't ass around, go get your fun!
