Tamron's last round of lens rebates ended on 12/21/11, but the good news is that they have a new set of rebates which run though 4/30/12.
All the lenses are available in Canon and Nikon mounts, most are also available in a Sony mount and some are also available in a Pentax mount. All come with a 6 year warranty.
NOTE: To claim the rebate, the lens must be purchased from an authorized Tamron dealer. That includes Amazon, Adorama and B&H Photo. Purchases from Amazon must either be from Amazon themselves, or an authorized Tamron dealer through Amazon (for example Adorama sell though Amazon).
If you MouseOver the links below you should see the current price at Amazon (before the rebate). Approximate prices after rebate are shown in the table.

I've reviewed quite a few of these lenses and in general I've found Tamron lenses to be well built and optically good. Their VC (vibration control) system is analogous to the Canon IS (internal stabilization) system and provides a similar amount of stabilization. The Tamron USD (Ultra-Sonic Drive) autofocus motor is analogous to the Canon USM (Ultra-Sonic Motor) and provides similar silent and fact focusing.
