I know exactly how you feel about the crash, man. It has happened to me many times. I have been flying for about 11 years now, but am only 21. I guess this hobby has just stuck with me. There are several routes you can take now....it just depends on what kind of person you are. You know yourself better than anyone here.
First option (what works for me): I would upgrade planes to something like the SIG Somethin' Extra (I have one). It has a fat wing, so it flies slow, but the roll rate is INSANE. I got the kit and it went together very quickly because of the minimal sanding needed due to 100% laser cut wood. This kit is totally 3D capable, but because it can fly so slow, if you set up your low rates right, it flies almost like a trainer. Inverted flight needs minimal down elevator to maintain level flight, too. I found that the recommended .46-.51 power is a bit underpowered. Get a .61 and pop it in there. Takeoff will only need about 75% throttle, though.
The Somethin' Extra comes in kit or ARF and you can buy all kinds of replacement parts for it.....wing kits, etc. One MAJOR downfall of this model is that it does not knife edge very well. I rebuilt the rudder on mine and added a whole 2 inches to the back of it....it doesn't even look awkward and I can knife edge much easier now. Get a good rudder servo for this model!!
I can also recommend the bigger U-Can-Do-3D model. Again, overpowering it a bit and starting off w/ low rates, it flies like a trainer (minus the self leveling since it is a mid-wing). This model also has a much longer tail than most so it is very easy to hover it w/ a slightly rearward CG.
Explanation: Ok, the above set of recommendations will only work for you if you have the DICIPLINE to keep these planes on low rates until you get more comfortable w/ the basic flying techniques....it sounds like you have a pretty good foundation, but still take it slow.
Second Option: Get another intermediate plane and pick up where you left off....get something different so you're not bored, but you will shortly outgrow it and will have to buy again. On the OTHER hand, do NOT get an Extra 300 or Edge 540. They are expensive and way too fast for what you've said you want to do. They are hard to land (because they are fast) and typically more fragile. Pulling out of a maneuver-gone-bad is sometimes impossible as they take constant "flying" to maintain good harriers and elevators. The fact that the U Can Do 3D and the Somethin' Extra harrier so well has saved me more than once when I'm close to the ground. The Extra or Edge in those situations would have snap rolled strait into the ground due to one wing stalling.

As has been said COUNTLESS times before....invest in a good sim like RealFlight G3.5 and practice all the crazy maneuvers you want. You can even learn how to do most of the popular 3D maneuvers right in the sim by watching videos of the pros do them on the sim right in front of you. You can also practice practice practice while you are building your new kit or ARF...it will help quench your desire to fly and keep you from doing a sloppy job on your new model. Don't just think of the sim as an "investment"...they really are fun to fly and on a windy/rainy day, you can plop down on the couch and play. The sim will pay itself off in 1 crash, but you will get so much better.
Sorry for the long post, but I know you want all the info you can get....I was in your position once and I know how confusing it can be. I'm actually in your position w/ helicopters right now
Not the whole crashing part, but only been flying about 1 year.
Good Luck!

P.S. The Kaos is a good choice too if you haven't noticed by the multiple posts recommending it......just thought I'd add that. (It flies kind of the like the Somethin' Extra....but the Somethin' Extra looks cooler :P)
