In reply to Euge:
I had a Kraken for a while - it was a good bike. The hydraulic brakes were effective, the suspension worked and it wasn't too heavy. With Halfords, keep an eye on their online offers - I ended up saving over $100 on the day, which I got to spend on more accessories.
I switched to a road bike shortly afterwards though, but managed to sell the Kraken at a profit (taking the tax-free bit into account).
