I can't apply for this coupon as I'm already a customer.
Anyway, Justhost.com is a good hoster. All my passive earnings sites are with them
I'm with JustHost since June and I didn't noticed any downtime. I have arround 11 sites with them, mostly WordPress blogs and my Twitter Apps. I can't speak about support, I don't need them
I have paid $24 for 6 month hosting and I'm pretty happy
