Hi, to be honest with you, ive just found airsoft through videos on yotube, i dont have any weapon nor kit.
but im wondering could one of you give me some basic backround on getting a cheapish gun online etc, also whats the minimum age of play etc
thanks
Best spend a week or so lurking and reading up on the kit and weapon threads,
There is no easy answer unfortunatley
It all depends on what nation and arm of service you want to portray.
You do however need to be 18 for CiA or PBI games.

Welcome to the forum 
Probably the best thing to do being new to this is to go to your local site and have a skirmish, most sites hire guns and will be able to fill you in on most things you need to know 
the main thing is to get out there and play 
Welcome
what are Cia and pbi ?
CiA Comrades in Arms i.e this forum and the people who organise the games
PBI Poor Bloody Infantry a group on this forum who do British units
As Gadge said spend some time looking through the forum and have a look at the kit guides, (accessable from the top menu), and you should be able to find answers to most of your questions
