OK....thx for everybody's opinions.

I know everyone has their own preference and both brands has their own characteristics.

steveng: yes...I own Alpine 7864 and 7894 before.

and guys, my choice are down to 2:
either the Alpine or the Pioneer Premier.

I know ordinary Pioneer "might" not be as good as Alpine,
but what about their Premier series (the P840MP)?
Are those still not comparable to Alpine's quality?

I'm considering Pioneer because I have always used Alpine, and I can't afford Eclipse's "retailer" price + labor fee
