Not a bargain but the SDS1104X-E 4-channel is only €90,- (ex. VAT) more than the 2-channel SDS1202X-E bargain price. SDS1104X-E is 100Mhz while the 2-channel SDS1202X-E is 200MHz. For many users a 100MHz scope will be more than sufficient. Both scopes are very good value for money.
Serial protocol decoding is included as a standard feature for which 4 channels are more useful (e.g. SPI) than 2 channels and often 4 channels are more useful anyway.
(There also is a 200MHz version of this scope: the SDS1204X-E. But that is 54% more expensive than the 100MHz SDS1104X-E, which is quite an increase.)

From the in-depth review:
The new Siglent SDS1x04X-E series SPO appear to have the potential of setting a new price/performance standard in the entry level class. The most striking features are:
- 4 channels
- Sample rate 2 x 1GSa/s or 4 x 500MSa/s
- Bandwidth 100MHz (200MHz for theSDS1204X-E)
- Memory depth 2 x 14Mpts or 4 x 7Mpts
- Up to >100k Wfm/s (up to >400k in sequence mode)
- Vertical true full resolution sensitivity down to 500µV/div
- Segmented memory up to 80000 segments for history and sequence mode
- Serial Trigger and Decoder (Standard): I2C, SPI, UART/RS232, CAN, LIN
- Full speed mask test
- 1Mpts FFT with Spectrum Analyzer-oriented user interface
- Automatic measurements use full record length with no decimation
- Full connectivity over USB and LAN (WiFi optional)
- Built-in web server
- Bode plotter for network analysis (Note: this requires a compatible AWG)
Additional options:
- WiFi (via USB dongle)
- External AWG (Arbitrary Waveform Generator) SAG1021 up to 25MHz
- External 16 channel MSO (Logic Analyzer) with 1GSa/s up to 14Mpts
(Articles are available on EEVBlog for how to upgrade to 200MHz and WiFi.)
