If your budget is $200,the best general purpose unit you will get will be a secondhand analog 'scope.
The US$400 DSOs often mentioned in this forum get a lot closer to $A700 when you take exchange rates,freight & so on into account.
The days of the "mighty Oz" being at,& above parity with the greenback are long gone!
Unfortunately many eBay sellers,seeing this increase in cost for new DSOs, have also increased their prices for old 'scopes to quite absurd levels.
There are still some Oscilloscopes on eBay for sensible prices,though,& there are other sources.
Look for Hamfests in your area----they often have a good selection of older test equipment,but sometimes don't.
The advantage of Hamfests & other such "swapmeet" style meetings is that you can ask to see the device operating.
Don't blow all the $200 if you possibly can find a ;scope at around $150 or under.
