The 4* is very inexpensive and makes for a great flying plane. For the price you cant beat it and its very easy to build. The Astro Hog flys well but the kit is a pain to build. Big blocks of balsa that you are supposed to carve, sand, and shape into an airplane. The Tiger2 is one of my all time favorites for flying well in a very wide speed range. The plane is larger than the 4* which makes it easy to see but is quite a bit more expensive. For a second plane I would go for the 4*!!!
