I am in need of a some help, I really am having a tough time deciding which route to take. You can see what I have below. Here are my choices as I see it. Each option will cost about 2400 minus what I'd roughly get for my stuff. I really appreciate your opinions.
#1) I could sell Xti get a used 40D plus a tokina 11-16 or sigma 10-20, sell the tamron and get a used Canon 24-105L.
#2) Sell Xti and get a new 50D and tokina 11-16 or sigma 10-20 and keep the tamron.
#3) Sell Xti buy a used 5D and sell Tamron and get a used 24-105L.
I know prices may be off a little but I think its pretty close. I shoot a lot of portraits, landscapes, and do occasional picks at sporting events (just for fun). I've done a couple weddings, nothing major though. I feel like I've just outgrown the Xti.
Please help with your opinions as I really am not sure which way to go. This is obviously a great time to pick up used gear.
