cheap guitars are 'usually' bad guitars. bad guitars are not easy to play - do not feel good or sound fine.
Do check out gumtree with a budget in mind. you can get very decent instruments at reasonable prices.
If it is for a first time beginner... I would recommend a classical type, nylon stringed instrument. The neck is wider and thus easier for a beginner to fret the strings cleanly.
