How much longer will you wait for a sub? Might want to consider towers to get you a little more in the low end. Infinity Primus P363's are in your budget and make a pretty good speaker for the price. They are on sale right now on amazon for 149.00, usually 199.00. Some times they go on sale for 99.00 but you gotta really watch for those sales. Don't wait to long to get your center, if speakers get discontinued you might have trouble finding a match. I've been there!
