Diode laser machine and training

[Blush89]

Hi,

im looking for some help and advise.
im interested in adding laser hair removal to my salon.
Ive read that a diode laser could be quicker than ipl.

Its the first time ive wanted to train in something that i literally know nothing about.
Could anyone help point me in the right direction of reputable trainers and machines/companies?
Do you tend to buy the machine outright? finance or rent?

Thanks
