My mom, sister and I all owned CHI's but all of them broke (mine in Malaysia, my sister's after a mere 2 months, and my mom's after about 1 year). After that I tried the Sedu and the Solia (both at folica.com). I like the Sedu, but i LOVE the Solia, I've had the same one since early 2005 and my mom and sister have both had theirs for nearly 2 years now...
I'd definitely say Solia, it's about $90, but well worth it.
