Good tournies to start with?

[Womble]

I play $1/2 6max and want to play a few tournies but I dont know where to start. I cant seem to find any good freerolls since they all have HUGE numbers of players for very little prize money.

What are some good tournies out there? I am looking for ones with good overlay (Is overlay total prize fund - [number of players x tourny entry NOT fee]?)

Found a gaurenteed $2.5k for $6 at ladbrokes which I think I may go for but are there any others?
