What's a good responsive testing tool (Browserstack alternative)?

I'm looking for a service just like Browserstack which allows us to test our websites on different devices. I thought I'd ask on here before I bought it as they may be a better or cheaper alternative?

I've been using Blisk. It helps!

RE:View is a Chrome Extension. Not as full-featured as Blisk/Browserstack, but fast & free.
