Honestly, I've been through this phase very recently and I did EXTENSIVE research for my second plane.
This is really the toughest thing to decide (what way to go next), you are tempted to buy beautiful airplanes, but you know deep inside that you are still not up to the level of flying a warbird, a pattern or a 3D plane

The majority or the general trend and good reviews from experienced pilots will lead you to a couple of choices:

1. Carl Goldberg Tiger 2 or Tiger 60 if you want a big plane
It can be bought as a kit or as an ARF, however there are lots of complains about the consistency of the product when it comes to construction.
Some firewalls were installed backward... You will have to rely on your chance or building expertise, but the flying characteristics of this plane are just amazing.

2. Sig Fourstar 40 or Fourstar 60 if you want a big plane
It can be bought as a kit or as an ARF. This is a tail dragger design and generally no complains about the construction or flying characteristics.
In fact it flies extremely well and lands very slowly.

3. World Models Sky Raider Mach II or LA Racer 40 or Super Sport 40
The Sky Raider Mach II has an another version called Mach IIs and it is basically just a newer trim with the same dimensions and design of the Mach II model.
LA Racer 40 is also the same design as the Sky Raider Mach II but with another trim still, and an additional cowl specifically cut to fit the OS Max .40LA engine.
The Super Sport 40 has also another version called 40s and it has a lighter wing load than the 40, a cowl around the engine and a different trim design.
All world models receive very high marks on the quality and ease of built as well as the fine characteristics in the air. These are all ARF versions.

You can go with any of the above options.
I belive the fourstar is the most beautiful out of all these, but what I did was settle for the LA Racer 40 (green trim) because this is going to be the first airplane I ever build, and I don't want to be facing problems with unproperly fitted pieces.
This is also a change from my tricycle landing gear on my trainer, and it is small enough to fit in my car.
It is somehow cheap to crash, so I fly it with less stress.
And I like to have two aileron servos: except for the LA Racer 40, only the BIG versions of the Sig and goldberg offers that... I will wait to have more experience before paying that amount of money on a plane I will easily crash :P
