Off Camera Flash - I Know Nothing :(

So a photographe I met today was telling me before I go on my winter travels, I need to get my flash off camera. What's the best way to do this thats most cost effective? With a cable or cheap pocket wizards? I know nothing about this stuff, other then the lighter and less clunkier the better. Advice would be greatly appreciated

Type of flash? And what type of shooting do you do?

Cheapest is probably a PC cable. Fraught with problems - people trip over cables. Cheap radio triggers are OK if you don't need them to fire every time, without fail.

Pocket Wizards are about $180 each - you'll need 2.
Cybersyncs are about $130 for a set, transmitter/receiver.
Skyports are somewhere between those two.

AB triggers

For ETTL, an ETTL compatible cord or, for a Canon flash that can use one, an ST-E2 infrared remote.

Thanks. I have a 430 ex and a 5D. I really want to learn about flash. I find it all so overwhelming cause I know virtually nothing. Any good starter guides to basic use of flash you know of?

This site helped me immensely for the on-camera stuff.

It can be quite daunting, but have a read through it, then use your flash for a few days and then read it again. It'll start making more and more sense.
