Hi Sharkbait,
We had one of our customers who bought a kite "cheap" in China for only $1000 AUD.

It turned out to be an unrideable piece of rubbish. The kite was a total waste and was only really any good for a wall hanging in a bar room. There are cheaper bar decorations around.

If you buy a lemon or it needs repair, you have no options and no warranty, or a back to factory warranty at your expense. I wouldn't touch it for $100
Support your local shop, at least then you get local backup and you are buying a reputable brand/name with some residual value.

What little resale you are able to get will be available to you, as opposed to zero resale of an unknown "no Frills" brand.
You always get what you pay for in life, especially with kites!
Hope this helps,
