Wow, you sure said large a lot
...I don't know what your definition of "large" is, but 1,100+ pieces (in the Malevolence) is generally considered a pretty big set by most people's standards. The only sets that have too many more pieces than that are usually Ultimate Collector Series, and there are generally only two or three of those available in retail outlets at a time, though at the moment there are four, and when
R2 comes out in May, that will make five. This seems kinda rare, but someone else would have to check on the history of concurrently available UCS Star Wars sets to verify its rarity.
With that said, here are the Star Wars sets currently available on the primary market with prices greater than $100.
Death Star - 10188
Pieces:3803 - $399.99
Super Star Destroyer - 10221
Pieces:3152 - $399.99

Millennium Falcon - 7965

Clone Turbo Tank - 8098

Among these, included are 3 of the 6 biggest SW sets
ever released (retail) by LEGO and all of these are currently in the top 25 according to
Bricklink. Which reminds me, if you're new to all of this, Bricklink is an excellent place to get old sets for reasonable prices on the aftermarket and Brickset is a fantastic resource for easily locating sets for sale on ebay.
