You can get Chinese knock-offs of the Saleae Logic or the USBee for $10, at DealeXtreme for example. They run fine with sigrok, and even with the original Saleae software if they report the correct USB Product/Vendor ID pair. They might not do the higher sampling rates, though.
If they don't report the correct USB IDs, you can reprogram the USB EEPROM with the Cypress EZ-USB FX2LP tool. The Linux version is a bit buggy though (converts hex data to 0-terminated char* before sending to the device and therefore can't write data with 0x00 in it), so I wrote my own little tool: https://github.com/DrMcCoy/FX2LPTool
Of course, that's "only" a logical analyzer, no oscilloscope.
