Ok. To make a long story short. I need to get another motor. Where can I get a dependable used or new 4g63t motor?

Hello to all. I live in MS. I love the eclipse, always have and always will. I'm, now, driving my 3rd and (hopefully) last. It's a black '98 gst with all leather interior. It's the one I've always wanted, and I'll drive it until it can't be driven.
