What about a second-hand Yoga 2 Pro? This should be in that price range now, roughly.

I've been using this for a couple of years now and was quite happy. It's a good trade-off between performance, weight and size in my opinion. Except some minor inconveniences[1], my Linux/Windows dualboot setup works quite well.

Heads-up: If you consider it's successor, the Yoga 900, make sure you don't get one of the series not supporting Linux (Google is your friend).

[1]: The biggest issue I've faced is inaccuracy of yellow colors on the display; they're dark and pale. Lenovo published a BIOS fix for Windows, but this doesn't work for Linux. However, if you don't plan to do any visual work like photo editing or designing color palettes, you should be fine.

I still use a yoga 2 pro. It's a decent machine, with 8gb ram. If you can find it at a low price definitely go for it.
