Is this a good deal?

My Canon Digital Rebel EOS XSi has three lenses that I like but the middle one (55-250 from Tamron) has been giving me problems. After every shot I get an error message saying the electrical contacts are bad. I've cleaned them several times with no effect. All I have to do is turn off the camera and turn it back on to continue shooting but obviously that's a poor solution. I've discovered that many others have the same problem and Tamron has chosen to ignore the issue.

I just saw an ad from 42nd Street photo for a similar lens from Canon (this one with Image Stabilization) on sale for $129. Here's a link to the ad.

Free shipping. Can you think of any reason I shouldn't get it?

Thanks,

Pat
