It's worth spending a little more on a compressor with a tank and water trap to start with such as Rik Lightstar links; you can upgrade to better brushes later, and you can keep using the same compressor. The cheap ones are generally AS186 compressors rebadged for around £80-£90, and they throw in a cheap chinese airbrush or two. There's also a slightly improved version with a fan that runs a little longer before overheating, the AS186S, like this one.
Having a tank means
a] the compressor itself runs to fill up the tank, then cuts off till the pressure gets too low. So it's quieter overall, and also runs for longer before it needs a break to cool down (around 45 minutes continuous use)
b] the airflow stays at the set pressure, without pulses of small changes, so better quality spray. The water trap also stops any water drops messing up the spray.
The chinese airbrushes themselves are basically disposable; you can't get replacement needles or parts, and they clog fairly easily, but they're fine for learning the fundamentals and laying down base coats. They can be fiddly to clean, but that itself will be good practise too!
If it turns out you like it, and want more control and ability to do finer work, it's worth then buying a badger patriot 105 or harder and steenbeck ultra 2 in 1. Both are great workhorse brushes without breaking the bank, and you can keep the chinese one for varnishing. I personally love harder & steenbeck brushes, as the quality is superb, while badgers feel a little like they're made out of repurposed iron pipe; but the end results with either is solid.
