I can recommend the Hormann. I recently had a new electric sectional Hormann door fitted, the quality is great, a really solid piece of kit. For a double garage, it cost me 3K fitted (which only took half a day). I'd expect a couple of side-hinged doors to be cheaper than that, it will depend on where you live of course - only way to know is to call up a few local tradesmen and get quotes.
