For starters, ebay may not neccesarily be your best bet, if you check the string "Heya guys, Newbie here" (At the bottom of the recent list right now) u can check out someone with a similar problem, i would suggest you try a different brand tho, the pic say they're rizers, but they're not even called Powerizer any more, so i here, and ones which say fly jumpers on, dont tend to be the best quality, in my experience, tho then agenn i've had nothing else yet, most will say that 7 leagues are your best bet too, maybe T Rexes for you, but as we're on the pj forum, i'll suggest them too, so as not to be kicked off, lol
