content: Anyone in Singapore letting go a cheap working o-scope?Those office recycling companies who peddle their scopes on evilBay are all either potluck condition (claimed to be 'can power on', etc etc) at around S$2-400, whilst those which are actually working sell for 5x more. Unfortunately, in Singapore, unless they explicitly state the item actually works, one can be sure it definitely does not work.I've already tried visiting some of those recycling companies, as well as 'buying the lottery' by foolishly spending ~$200 on a few scopes in the flea market in the off-chance I could revive one. No luck, all beyond repair.I was hoping my budget won't exceed S$100-200 as EE is still only my hobby and I am still studying chemical engineering in a local polytechnic. I can't afford a Rigol/Hameg/Owon/Thingamajig at this point, and I am not going to resort to getting the DSOQuad/UT81x no matter what.

There was more noise than signal on the few random things I tried measuring with. Even after I shielded the testarea & scope with layers of tinfoil, there was still so much noise I could not tell the difference between a PWM signal and a ~sine/triangle wave.The UT81 is out because I bought it once, and the waveforms were too slow and hung half the time so I returned it.

Yes you could buy brand new digital scope @ 25mhz from ebay for about slightly more than Sg$200.Becos you are a novice you are unable to repair those analog scopes you bought,however if you know where to go there are bargains to be found in singapore vis a vis ebay.Email me if you are interested.BTW I'm not a reseller of test equipment.Prices here are high but what to do?
