Re: What fixed bridge Ibanez ?
If you want to go cheap on a fixed bridge Ibanez an RG321 (mahogany) or RG3EX1 (basswood) would be a good choice, there are a few more similar models of similar quality that I can't think of off hand right now. Just try to play it in person, because the fret work and overall quality control can be random on these. Same with any guitar really.
They may be cheap, but find one that's set up properly with no fretbuzz and I think you'll be surprised by what you can get for your money. About the comfort/feel, Ibanez necks are very flat and thin, but they are also wide. Have you tried an Ibanez with a Wizard II neck?
