Richer Sounds have a deal on at the moment for a TEAC DAC for £150 whereas the normal price is £300!
Be sure to review the specs of the DAC. Many cheaper DACs are limited to 16/48 in USB but a better DAC will do 24/96. Likewise, when it comes to optical and coaxial they're almost always at least 24/96, from what I've seen.
There's also a bit of a difference in how they get to your DAC from your computer. They're both digital but they're also different interfaces. They work in slightly different ways.
As for whether or not a £40 DAC can compete with a £150 DAC, it depends on the DAC but my gut reaction is yeah, you'll get something more for your money. At that price range you should start expecting to get 24/96, for a start. You could probably get the Audioengine D1 for that price, though. I'm not familiar with TEAC so I can't comment on the sound.
