I have one, which I have not really used.It feels solid and the modes are well spaced out and regulated.Nice, floody, beam.There is a hidden flashing mode that is a bit diffcult to get quickly.Reasonably bright, with a good compromise between brightness and operating time.You should be able to get one for under $20.

I too have a blue G2 on the way.
Happy with it?
