I was wondering if you just buy park tools first time
I rarely buy Park Tools. I think they are expensive for what they are.
Most general tools (Allen keys, sockets, ratchets, spanners, cable cutters, files) can be bought at just as good if not better quality elsewhere. Halford tools, for instance, are brilliant quality. I got some new Allen keys off ebay, the same make as I had last time, because they had lasted me nearly 10 years (I lost the most popular size and snapped a 2mm one)
Stuff like chainwhips, cassette tools, cone spanners and BB tools I buy as and when I need them, and budget tools are fine in most cases. My cain whip and cassette tool cast me £5 each from one of those one-day sales.
So, yes, buying tools is definately worth it: Spend £15 on tools rather than £10 getting a bike shop to do the job and the next time you're in profit. But don't just blindly buy Park tools just because they are 'for bikes'
