I need help choosing the right slr lenses for a canon rebel xti?

I want to get into photography but i have no clue on which lense to start with. I am mainly going to be shooting people pictures like portraits and out doors. I want to know what are good lense to start with and are not really that expensive. No more than $150

We pretty much shoot the same thing and this is what I got (in order of the date that I got it)

18-55 Kit Lens - used it for several months, you "OK" pictures for this lens and it is a good enough walk about lens

But I suggest you get the

50mm f1.8 - insanely cheap and great for indoors, lowlight and portrait. It creates beautifully blurred backgrounds. You can get this for as low as $75

After a couple of months, I needed a standard zoom lens and I bought a 28-105 f3.5-4.5 II USM for about $150 brand new. Good upgrade to the kit lens and the images are very sharp.

Good luck!

Well that budget isn't going to get you much. Maybe start with the XTi bundled with the kit lens. Tack on a nifty 50 f/1.8 and call it a day.

get the 75-300mm if it goes on sale and use it like a pair of binoculars like me..good luck
