I have been hosting my sites at Gigapros for 10 months now and love them! You get so much for your money and I've had nothing but excellent experiences with customer support. As for uptime, I've never experienced any major downtime apart from when I started - I would have 20 minutes of downtime but these days, it's near 99.9%.
You can make your own backups too and retrieve a file which you've accidentally overwritten or deleted from the directory.
I LOVE IT!
