I have 3 Ibanez guitars if you count my bass and really like all of them. Great bang for your buck, and they just feel good!
Ibanez is definitely known for their shred sticks, as AlexR says. I play classic rock, and the only thing I shred is cheese! That being said, my RG is a cheaper one (RG3EXFM1 - $350 new in 2010) but I find the thin neck to be quite comfortable to play. I wasn't crazy about the stock V7/V8 pickups, though and replaced them with some GFS Dream 180s this year, and it's a classic rock machine now. I have a long history with my number one, so this one generally doesn't get taken to gigs, but it has easily taken its place when needed.
They also make some wonderful semi-hollows if you're open to them. Definitely NOT a thin neck there, and 24.75" scale length. My 2005 Artcore AS83 plays like a dream, but I had to upgrade the pups on that one too, from the stock ACHs to Duncan P-Rails. This one goes to gigs with me simply because it's so much fun to play... and it does classic rock VERY well!
So yes, Ibanez are popular and well-represented because they're known for being metal/shredding guitars, but don't let that fool you into thinking that's the only thing they're good for! [emoji6][emoji1303]
