treadmills?

Does anyone know anything about treadmills -- as in, recommendations for what a good, but relatively inexpensive brand/type might be? I'm considering getting one, and don't want to get something cheap that ends up breaking down in 3 months, but I also don't want to spend a ton of money on a top-of-the-line machine that I won't make full use of. This article is helpful, but it doesn't name specific brands or models and not being in the know I don't know which are trustworthy/reliable, etc.

Thanks in advance!
