Your 1700 should be fine running a 5.1 setup. A question we like to ask around here is how big your room is. That will help determine what size the other speakers need to be.
If you're on a budget and you have a modest sized room, I'd recommend the Axiom QS4s for surrounds, and the VP100 for the center channel. This would come to $640 for the three speakers. Now for the sub...that one REALLY depends on the size of your room. So I'll hold any recommendations until I hear back from you on that.
As a side note. If you order direct the delivery is only 2 day air via Fed-Ex. If you order from the Factory Outlet it will still be two days...plus whatever length of time is stated on the webpage for wait time. The link is on the home page. Most of them seem to be between 1-5 weeks wait time.
