if I had 3K to spend, I'd go on holiday & use the kit I already have - It's old, but works just fine.
I just read through this thread. I am totally shocked that only one person came up with the right answer (see quote). With the OP's gear, and $3,000, I'd buy a 10-22 and a plane ticket to Hawaii, or New Zealand. It seems gear-heads and G.A.S prevail in this neck of the woods.
