Do you really need two bodies? You could sell the T5i and pretty much pay for a used non-stabilized Sigma 50-150 or 70-200 f2.8 HSM with nothing out of pocket.
It has always been my intention to sell the other body. It's just getting an offer on it that isn't going to smack me in the backside that is the hard part. Given that it's not that old I don't expect full retail back, but i also don't expect just 300$ either.
I got to mess with a tamron lens today at the local shop and it felt better than the canon one. Sadly I've misplaced my canon promo code to get like 15% off so I think I'm stuck getting the tamron instead of canon
Thanks for the tips on the training/learning websites. I will def. check them out.
