welcome dude, my first 7 was a 7321 too and i bought a K7 after that, and whilst i still play my RG7321 i have to say that the K7 smokes it in every possible way (obviously) it's just a fantastic looking and sounding guitar, and stupendously versatile so its a good upgrade when you get around to it.
and as for ibanez being a rubbish brand, well it depends what you play from their line up, the 7321 isnt bad at all (esp. for the cost) throw some new pickups in there and im sure you'll get along great with it
