All guitars can last. Unless you treat them bad.
Why the preference for cosmetics?
Also, MIK does not mean inferior. 2nd handed are good too.
Why the burning need to spend so much for your first Ibanez?
razer, I've noticed you deciding and choosing a guitar for some time but to no avail. Are you the type who is all talks, no action? In any case, with the budget of $1.5k, You needn't spend all. An Rg350 will surely fit your needs. With the balance, you can use for maintainence and future upgrades.
I'm not against people owning expensive guitars, but I'm against people wasting money. Should you be interested a review of the Rg350 can be found here :

Regarding your decision to change "parts,pots,pickups etc." .
there isn't a need to change every single part of the guitar, unless its of an inferior grade. The Rg350 and up have good hardware, save the pickups which could use an upgrade. Then again, if you're not an avid performing musician, why upgrade? Wasting money? You don't have to customize every single part of the guitar ; its not a haro bike, mind you.
But other than that, I'd recommend that guitar above for starters, and to hold on to your cash till you know what you truly want.
