Yes, IHC rides are good to start with. My very first HO ride was the Faller Rainbow as i have always been a fan of the ride since 7 years old. The Faller rides aren't much harder, you have to take your time, have patience, and in the end you will have a very nice ride for your carnival / park layout. I don't suggest the Faller Log Flume kit, that thing is Tough!! I tried to build it, but didn't get very far. [:(] Next time i attempt the Log Flume, i'm not adding every single detail to it, just the water troughs, log cars, and the stuff it takes to get moving..that's it.
