Single line VFDs from fruit machines are available cheaply on eBay and nearly always have an SPI interface so can be easily interfaced with any PICAXE that supports hardware SPI. But best of all, they are massive compared to ordinary HD44780 LCD and HD44780-compatible OLED displays.
The OLED display (right) is a lot bigger than the ones Rev-Ed sell, and yet it is still small compared to the VFD. The VFD is about 20cm across.
