I was amazed at the amount of times that people did not have defuse kits tonite.
My buy scripts are set up so that the first thing it buys is the gun followed by the defuse kit and then all the other stuff (bullets, armour, nades etc). Have a look at my buyscripts for CS 1.6 in the public forums (http://forum.deadmen.co.uk/index.php?showtopic=2776&view=findpost&p=27293) to see what I mean. If your defuse kit is bought as part of your script then you wont forget it ;-)
Hear hear. Or is it Here here?
