>Are there certain parts that always break?

Yes, probes. Always have some cheap probes available that you normally use,
and keep the expensive wide band/high quality ones in a draw for when you
need them. Probe leads always manage to get tangled where you least need
them and get pulled so that the inner core of the coax breaks or goes
intermittent. If you can find cheap probes with a replaceable lead, they may
be worth investigating.

You will find that cheap probes will generally be designed for 50 or 100Mhz
bandwidth, so with most scopes will not be too limiting. It is only when you
go to a 200+MHz scope that the differences really become apparent.
