The PIC16F1454 is a great alternative to common USB to UART serial bridges out there.

Pros:
- Less than $2
- No Crystal needed
- Small pin-count, 14 Pin DIP / 14 Pin SOIC / 14 Pin SSOP / 16 Pin QFN
- Through-hole option
- Small size, QFN 4x4mm
- Customisable

Cons:
- My firmware uses the OS's default CDC drivers (Microchips VID PID)
- Not pre-programmed, need a programmer
- I haven't added TX/RX status LED pins yet, but easily added
- Although the firmware works well and I haven't come across any issues yet, it hasn't been rigorously tested, and may not be as reliable as known brands

Example firmware on my github. https://github.com/johnnydrazzi/USB-Stack/tree/master/USB_Stack_Examples/CDC_Examples/CDC_Serial_UART_Example
