Recommend me a cheapish tablet

I'm in the market for a new tablet, want to get a Windows RT or Windows 8 one. I'm a budget of 400 euro, probably the equivalent 400$ give or take, could stretch to 500 if it felt it was reasonable.

Was looking at the Asus Vivotab Smart. I won't be using it for any x86 app's because I already have a Macbook Air, just want a light Tablet for casual browsing and absolutely love the UI of Windows RT/8. Don't like iPad's and I use Android solely for development purposes.

Maybe it's a bad time to be purchasing a tablet considering Intel's new chips are out/coming out but I don't want to wait till the end of summer to purchase one.

Any ideas?
