Good afternoon, Andico...
Unless it's going to be a feature of your playing, I don't think I'd advise any guitar in this price range with a vibrato ('whammy bar'...). The good guitars get away with it, once up in the 'pro' league, and with a tame technician to match, but, in my opinion, they're an unnecessary source of trouble, especially when learning, in almost any style. If you really need it, go ahead, but I'd advise looking at other models without this accessory that have the features you want. No guitar in this range will have an inherent 'staying in tune' problem, whatever the make; Ibanez have an excellent reputation, but so have many others. Your call, naturally, but holding its tune should never be an issue, especially for one's first guitar.
Disclaimer : I've never had a use for a vibrato of any kind, as 'dive-bombing' is not an effect I affection in my playing. If I had to have that effect, I'd do as our son, Our Eldest, does, and use a detune pedal (think the dying notes of 'Karma Police'...).
Hope this helps.
