Absolutely!
OP:
www.ritebrew.com always has great prices on kegging items!
www.homebrewing.org for kegs. Check out the "loose handle/bottom" used kegs. I've got 6 of them, and no issues. Only two were loose on the bottom. A little Gorilla Glue, and they were as good as new. Cheap shipping also.
Try and find a co2 tank local on craigslist.org . Don't buy a new one. Most places only exchange tanks, so your shiney new tank will be bye bye your first fill. Save the money and get a used one.
Taprite regulators are the best bang for the buck. Great quality, and I've heard their customer service is second to none. You can find new ones on ebay for good prices.
Buy your tubing on amazon.
Use 3/8" ID tubing to control foaming.
Buy forward sealing faucets. Don't waste money on the cheap ones.
Just about anything made from stainless is worth the money, in regards to kegging equipment. (Except keg quick disconnects. They're a huge waste.)
MFL connections are your friend. Once installed, they make like easy.
***Also, keep an eye on the For Sale section on this website. There are great deals popping up all the time. Check a couple times a day, for it's a very active forum.***
The older used soda kegs are a high quality, and much more durable than the China/Italian kegs sold nowadays. Easy to rebuild, and will outlast these new knockoffs. The quality is in the details. I wouldn't buy any of the new kegs...
