[LAU] All i want for the holidays is a SPL Meter. Please help me choose a good one.

Folks, When my mate asked me what I wanted for the holidays, i looked over at my audio system and said "I want a sound pressure meter." So i'm looking around and of course the price range runs from cheep Radio Shack digital one to hundreds of dollars for professional Class 1 models. I'd like to spend around $100 - $125 and get an accurate meter so i can adjust my speaker positions, room treatments etc. So i'd like accuracy to at least 1 db or more, a display that will give me 1 decimal place, a bar that will show me levels over time. I'd love to be able to get the data in to my computer and have an gnu/linux program to display it, but that's probably past the $125 mark. My speakers have a range of 22hz - 35 khz +-3 db so if i could detect that range that would be great, but that's probably also over the $125 mark too. Any recommendations? Thanks a lot. Bearcat M.
