I have a Swix one I got from one of the Backcountry.com deal sites for like 30 some bucks. The DaKine and a few others are all basically the same exact iron just diff colors etc. DaKine and OBJ have complete kits with the iron as well.
All of those chassis irons are the same. The rotary wheel is kinda janky but mine works fine and everyone I know who has one it works. The temp control gauge sometimes doesn't match actual temp too but I always adjust temp based on how it melts not a pre-set setting.
$6 at walmart...it's better than Dakines and Bakoda which I also own. Both of them are fine for all weather wax but when you get into the harder tech wax they're not hot enough to melt them. They're a waste of money...get a normal iron with adjustable temps and just make sure you dont burn the wax. And save yourself $30
