I have a Huawei Sonic (successor to the Ideos), cost $180AU unlocked and I like it very much. My previous smartphone was an iPhone 3GS. http://projectgus.com/2011/08/huawei-sonic-review/ . Specs are not high end like the phone mentioned in the article, but its very usable.

Check out the Huawei Ideos X3

The Trekstor Smartphone is about 80€ unlocked, but is worse than the Blade.
