Timing-light kit and vacuum gauge query

[Jonesy_sa]

Hey guys,

Two questions:
- I need to buy a timing kit and was curious if there is much between them quality wise? I noticed allot of cheap Chinese ones. Is there anything I should look for in a kit?
- vacuum gauge: I use to have a car magazine with a great article on using vacuum gauge to diagnose issues such as air leaks etc (since misplaced) does anyone have a link or article describing this?

Cheers
