the newer ones will have IS, the older ones do not.
Generally, 3rd party lenses from Sigma and Tamron will carry less resale value (and a higher depreciation rate) compared to OEM lenses.
With that, the Tamron 17-50 is a cult classic among crop shooters. The newer Sigma 17-50 (with IS) is the best lens in its class, for far less than the Canon/Nikon equivalents (17-55s).
You can't really go wrong. If you save up, you'll be getting a high quality OEM lens. If you choose Sigma and Tamron, you get a great lens at a great price. It all depends on where you want to put your cash.
If you can find one, I had a Sigma 18-50 2.8 "macro". I loved that lens to death and only got rid of it to fund a Canon 10-22. The close focusing distance (while not a true 1:1 macro) really gets you close-up photos without breaking the bank. It was my go-to when shooting crop while I had it.
