Peter, I noticed that you spelled a word or two using the "Queens English" are you outside of the US?
While it is tough to go wrong using kits/components from the (major) suppliers, as a Canadian I find sometimes it's the cost of shipping that tips things in favour of one or the other - plus there are some suppliers that just don't want to be bothered shipping outside the US (understandable, some items I receive have two trees worth of paperwork attached).
So if that's the case there are a few of us "foreigners" on the site and can maybe steer you to suppliers that are well versed in shipping across borders.
As to your question about barrels, I like Rice, Colerain, Green Mountain and Oregon - haven't listed the others because I don't own any, but the answer would probably be the same.
Tough to go wrong with any of the current barrel makers. Sometimes it comes down to who has what available at the time you are ready to buy or who has the profile you are looking for and you don't want to wait, sometimes many months - the one man shops tend to get backed up.
