I buy the Fudge Skrewd from a local hairdressers so you could check out hairdressers in your area or you to somewhere like www.hqhair.com and order it there.
It £8 but it lasts ages as you don't need to use a lot. It's a thick, gel like consistancy but not sticky. It gives really good curl definiation and as it's heat responsive you get extra boingy curls if you use a hairdryer.
Good luck! Let me know if you do buy it and what results you get.
