Hiab course advise

Hi guys . I’m thinking about hiab course.not sure what to choose.
Do I want itssar or allmi?
I found one for 360 pounds. Remote. Hook.itssar
Or 520 allmi remote and 2 attachments. When I look at hiab jobs doesn’t really say what attachment do I need so not sure how it work . Thanks for any replies

Dont take it as gospel but…

As far as I know ALLMI is the most recognised.

Where I do my CPC they sometimes offer a ‘free’ attachment,which is a choice of 2 attachments from the 3. Hook and brick grab being the most popular, or swap one for clamshell bucket if you’re on the tippers. I think they charge about 3-400 for the two day ALLMI remote.
