Let's see, here are 2 different discussions:
1º- which oscilloscope can be bought in the Philippines? If only the Rigol or the Hantek has a good price, the choice is clear Rigol, by the amount of memory. Rigol is not the best oscilloscope, but at 400usd it is very well priced and is a good option.
2º-What is the best oscilloscope in this price range?
Rigol ds1054z is fine but today a little slow and there are already better ones, even so it is not a bad option to start.
GW Instek GDS1054B vs Siglent sds1104x-e, in Europe they have the same price, but the characteristics are the following:
GW Instek GDS1054B:
1 ADC at 1GS = 250ms in 4 channels
Wfms / s: 50,000
Screen 7 "
Serial decoder: in the new version of software yes, but I'm not sure if it's free??? and use all secuence memory for decode??? MODIFIED
Possibility of signal generator: NO
Possibility of logic analyzer: NO
BodePlot: NO
Siglent sds1104x-e:
2 ADC at 1GS = 500ms in 4 channels
Screen 7 "
Wfms / s: 400,000
Serial decoder: YES, Serial / RS232, I2C, SPI, LIN, CAN
Possibility of waveform generator: YES, needs expansion
Possibility of logic analyzer: YES, needs expansion
BodePlot: YES, you need any Siglent waveform generator or expansion
Another good option is the Micsig TO1104 Plus, it is a bit more expensive but it has a battery and it is totally portable, 4 channels, 100Mhz, 28MBs, 80,000 Wfms / s, 8 "touch screen
