New or Used? Just 1K on speakers alone or does that need to include a reciever?
I'll admit I use my Promedia Ultra 5.1's for HT duty....BUT...my room is very, very small(like 7'D X 9'W). I am 6' from the screen on the couch using a 27" HDTV, if I was sitting I would be able to tocuh the screen and my nose. I have a DD5.1 collecting dust that originally did the decoding/preamp for when I had the v2-400's, but then got a Technics SH-AC500D as my preamp. Granted I only have the HDTV cable box, and my HD-DVD player, but thats all I need. It does the job for such a small room.
If you like the look and feel of the Promedia's, maybe look at the quintet setup.
You might be able to use the SWS, as I believe it just takes a line in. This is atleast what I can tell from the manual. I've been tempted to try and connect my spare sub to the SWS out off my ultra's but haven't yet. The SWS does pretty good from what I heard, and may hold you over till you can get a bigger sub.
The STIG's fat cousin.
