Default Fast programmer for stm32

I am looking for a fast programmer for STM32 devices. I am working on a device that has 2MB flash and the JLINKV2 just takes too long to program.

I have looked around a bit and the SEGGER J-Link Ultra+ seems to be fast at 3MB/s but it has a high price tag to it. I was wondering if anyone can recommend a cheaper alternative that is quick?

The STM32 chip has a built-in serial bootloader, but it isn't that fast in reality. You can load your own bootloader using this, and load the main firmware using your own USB bootloader. This way, through the use of USB bootloader, you can saturate the writing speed of the Flash.
