I recently got the Orion Cheshire from Bintel...it works a treat...
Since I 'd never "collimated" any scope before I asked the guys at Bintel to do a quick "how to" in their shop...it was very helpful...we used the floor display of my scope...
Although much slower by myself at home, I was able to do a decent job on my first attempt...
I've played around a bit since then and each time I've gotten better/faster at it...
I'd recommend the Orion Cheshire Collimation tool
