lessee... given the budget, i'd spend 500 on the avr, and 1000 on the sub...
pio 1018 seems to be popular and fits the (theoretical) budget breakdown... sub forum would be the best place to look for sub recommendation, but i'll warn you, you will get MANY different opinions...

a few people who's opinion i respect seem to REALLY like the rythmik subs (sealed, please), and you'll get a lot of positive feedback on svs and hsu...
good luck, and remember it's supposed to be fun...
