I didn't like the CR's shallow rear dish at firs either. Once I got my wheels built and looked at it long enough it really grew on me.
Best advice I can give is to look at as many different Cobras as you can. Then sit down with a pen and paper and write down all the features that are important to you ie body shape cost etc. Prioritise them and then go look at the different kits with those priorities in mind.
Ask lots of questions on the forum here and your sure to get a bunch of useful info back. Some of it may be coloured by personal experience good or bad but you will get a feel for which kit will suit you.
Cheers
