Instead of a D30, put a Digital Rebel (300D) + Grip on these lenses.
50 1.8 II
My whole setup goes something like this:
18-55 EF-S mostly @ 18mm
28-105 3.5-4.5 II USM and
100-300 5.6, but are on their way out.
Filters, tripods and a sick Lowepro backpack to haul it all in.
And a Panasonic Lumix something for parties.
