Hey there cat, first welcome and if you are interested thank god, and then can I sugggest if you are on a budget then some skyrunners from the skyrunners australia. They are what i use and are a very good introduction , and for me have been keeping me going for about 3 years know. Powerisers you may still have in your budget but if just wanna try and not blow the bank which is what i did then deinateley give them a go.
You will hear all kinds of slagin about these stilts , but trust me, the stilts i have been using i have no dramas with and they will get you on your way. Alot of the critism comes from Europe so in the land down under we use the most of what we have and that is what i can say about my stilts. I have't replaced anything except my hoof pads which are the feet rubbers that get a work out, so this will happen over time anyways no matter what stilts you get.
Hope this helps, SKYPIRATE(aka Adam)
