lifting at home

[ActionJeff]

I'm getting tired of having to drive to my gym every day, so I want to get some equiptment to lift at home.

I don't have any weights right now, and space is not a major concern. I do various freeweight exercises, squats, and bench. I don't want to sink a ton of money into building a sick home gym or anything, but I want to be able to do reasonable lifting the days I don't feel like going to the gym.

so

(1) Whats the min I need to do safe squats at home?
(2) what type of equiptment should I get? Are adjustable dumbbells preferable to a normal dumbbell set? etc
(3) should I buy this stuff at a local place or just order it online, and what websites/brands are best to get?

thanks
