I know you're on a budget, but to be realistic, you're going to have to spend around $1000 on a decent set of pipes, bag, and reeds. Mr. Woolery has pointed out some good deals, and I myself play MacCallums, but there's three things I'd recommend you look for in beginning pipes:
1)Synthetic bag - zero maintenance and a zipper which makes fishing out reeds MUCH easier
2)Synthetic reeds - purists prefer cane, but I have some carbon fiber Naill drone reeds, and they provide a deep, full sound that really carries.
3)"easy" chanter reed - Get two easy strength chanter reeds, break them both in at the same time by alternating them, that way you'll have a backup if one gets damaged.

Hope that helps. Don't buy Pakistani pipes! They'll just cause headache and frustration!
