It comes down to how much use you wil get out of a tool like that.
If you plan on building a lot of Aircraft, and punching out a lot of Instrument panels, then a punch set can come in handy.
I bought one that I came across just because it was cheap...not because I felt I needed it.
And because it had a .5mm punch (with .5mm increments).
I didn't expect high quality, but I was VERY surprised this set:

But...To be honest, its easier to grab a fresh #11 blade and put on my 4X reading glasses
and do it manually.
Keep the blade upright, perpendicular to the part...
Don't try to drag or move the blade in a circle!
Make little stabbing cuts all the way around the hole you want to create (until a round part is removed).
I've cut some very small holes this way.
...with a little patience, and a steady hand, you can do this in under 5 minutes:
(This panel was cut by my hand before i bought my punches)
