Hi , i bought a 7.0 beamer as a cheap low wind buggy engine , about 2 months ago .
It works very well , after a little bit of adjustment ! and i would say it is a very good kite for the money and flies really well , very little luffing and very easy to fly.
I've also got a 5.5 buster and that also flys very well , but i did try a 7.0 buster and found that quite slow compared to the beamer , so i went for the beamer in the 7.0 metre size .
Hope this helps !!! Dominick:)
