Ditto on the "Big Island Revealed" (We're planning our trip for May) Also,
KONAWEB - Online Resource for the Big Island & Kona, Hawaii has been very helpful and on their site is a link to a shore diving site for Kona
LET'S GO SHORE DIVE'N' on the Kona Coast
And while I can understand the budget, I think you may want to consider splurging and doing the Manta Dive one night. Everything I've heard about it indicates it's a truely awesome experience. DH and I are doing our Boat Dives with Wanna Dive Kona. We'll report back when we return.
