Thanks Paul.
I thought the Bintel sounded like a good deal but being new to this I wasn't sure. It's hard to compare when you don't really know what's useful and what's just a gimmick they've thrown in to trap the unwary.
I'm leaning towards the Bintel now.
I've certainly seen plenty of recommendations on here for Bintel's great service and so on, so it seems like a safe bet.
Cheers,
Cathy
