RE: Best Second (But ARF)
If you are looking for a high wing the World Star 40 from world models is great. It's got the durability of a trainer but no dihedral so it does a great job with beginning aerobatics. It also has flaps. It's built to take punishement and usually sells for $99.00.
If you want low wing the World Model Super Sports 40 is even better for the same price.
There are alot of great ARFs but these two are a good value for what they offer.
Good luck and have fun!
