I really like Mavic Aksiums as do it all wheels. I have three sets now(long story) which have used since 2006 and gone from 110kg to now under 90kg but throughout have used them off road, commuting, weekend rides etc. Even recently took a hotly contested dirt track KOM( due to a tailwind) with them and 23mm tyres, they are IME tough.
Throw away the tyres that come with them though, there the devils work.
Edit: just noticed your budget, quite a lot for a commuter but if you did want to spend that and considering your largess perhaps some 32h handbuilts.
