Phil - my assumptions are:

1. you have some level of piloting skill on 2 channels and you want to move up
2. you have your own 4-channel radio equipment that you can use to a new plane
3. you have access to a big stick that nobody flies right now
4. you have glow plug lights, starter and starter battery
4. you have $150 budget

couple of questions that you need to answer.
1. are these assumptions true? what is and isn't?
2. by "durable" what exactly do you have in mind? you can't expect any plane to be stomped on by a gorilla like a samsonite suitcase.
3 do you have access to an instructor?
4. how much have you invested in electric accessories already? nice charger, some li-pos
5. do you like electrics and want to stay electric in the future?
6. how serious are you about going scale?

there are so much advise we can give but you need to give us some guidance.
