I recently came across a low cost usability testing service provided by UserTesting.com They have already worked with some impressive clients including CNN and Twitter. The co-founder of Twitter said ‘Use it, and your site will get better‘. I would have to agree.
This innovative new solution allows developers, designers and digital marketers to quickly and cost effectively identify the usability issues with their website. For about $30 per user you can quickly specify your target demographic and test your sites usability for specific tasks. It is widely accepted amongst usability experts that 5-6 users will probably identify about 80% of the issues with the site. So for around $150 you will get 5 usability videos and user feedback related to a specific task on your website.
Another great cloud based cross browser testing tool is http://www.cloudtesting.com/serviceCrossBrowser.phpLooks powerful and could be done in conjunction with User Testing to assess additional browser related issues
