As a fairly recent newcomer to bass myself, I would very much listen to the advice on here. These chaps know thier onions, and thier basses too.
Forget about image, you are learning so you need a bass that is comfortable and easy to play. You say you want to sound like flea, well that aint gonna happen, because flea is a person, not a bass. He could make any bass sound like flea. Flea himself could hand you his bass, and you still wouldnt sound like him.
A squier Vintage modified Jazz is an amzing bass for the money, the slim neck makes playing a breeze and it looks great. The Ibanez is also very nice, but a completely different tone to the VMJ. Again, the neck is really slim, so easy to play.
Another point. If you are not sure you can or actually will want to carry on playing the bass, then you need to think about resale. A VMJ will hold is money easilly. Those package basses wont and you will loose a lot of money in a short time. I know you have a thing about 2nd hand basses, but I have bought all my basses off here, and bar one they have immaculate. You will get so much more for your money on here, and you wont get screwed over like you will on ebay.
Im sure if you asked nicely, a seller would strip the bass and clean it up as new for you.
