Mary,

The blokarts have become very popular over the last 3 to 4 years and so in some places a rather healthy secondhand market is starting to pop up.

Maybe you should look around on one of those Ebay sites and see if there is one on offer for a nice price.

You never know. If you don't buy it too dear then you can always sell it onwards for the same later if it isn't your thing. Just make sure that you have an area nearby that will allow you to use the thing.
