I'd consider an Arcam AVR-300. If you don't need the 6th and 7th channels, they can be bridged to bi-amp the front channels, giving 200 watts to the fronts and 100 to the other three. This is how I've arranged my system.
The AVR-300 gores about $1800-1990 new and a few hundred less used, so this would leave room in your budget for speaker cable retermination, if needed.
Such an arrangement might be WAF/space friendly, which is why I chose it over a two-box separates solution.
Just a thought...
