Hi Trinitrophenol
You could always pop over to China and get them from the factory

Seriously though have a good read through the forum and do a search for threads similar to this one theres loads of advice on which are the best
My personal opinion is that you cant go far wrong with a set of Pro-jumps (I've got 4 sets now

) there are a few types to avoid (normally the really cheap ones on e-bay)
Your best bet would be to get a set of whatever brand of the Pro-jump range they sell in your area to learn on
Then if you are really serious and want to go on to better things import a set of Powerskips from Austria (out of you price range at the moment but if you go the way most of us do you'll sell your Grandmother to get some

)
Now the good bit what type are sold by you you need an expert on types and areas sold in
SPROG! SPROG!
If we all shout Sprog loud enough he will come up with a list for you

Alternatively PM him and ask
