New to kegging

So I've been reading a lot about kegging and I would appreciate any additional insight anybody can give me. I have a fridge in the garage that I am planning on using, full size, but has the freezer on the top. I think I've decided ball lock kegs are going to be my best bet and I located someone in my area that has corney ball lock kegs for $30 that were reconditioned not too long ago. I want to be able to use the corney kegs for my brew, but I also want the ability to hook up a commercial keg should I decide to. I am trying to stay economical to begin with, I don't want to skimp, I just don't want to be buying everything top of the line. Any suggestions on a good setup and where to get it? I was thinking I want 2 taps to begin with and figure I will add more later. Is it easy to switch between corney and commercial kegs? Thanks in advance for any info you can give!

In order to have 2 kegs and be able to switch between Corny's and Sanke you will need a CO2 manifold with 3 outlets and shutoff valves. The connectors are available from all brewing supply stores. Grey = CO2 connectors and black = Beer connectors for Corny kegs. Use 5 to 6 feet of 3/16 vinyl beer tubing for each black connector to the shank going through the door. These shanks should have a nipple and washer for 3/16 beer line so you would need 3 washers and 3 nipples with nuts to connect to the 2 shanks. You need 2 ea grey connectors and 1/4 inch beer line to connect them to your CO2 manifold. Now for the last item the Sanky connector which is used to tap Sanky kegs. These cost around $28.00 and you need 5 feet of tubing for the CO2 and the beer with nipples and washers. Note that I have already told you to buy 3 niples and washers for the shanks so the third nipple and washer is for the Sanke to shank connection. You need 2 beer faucets of your choice(I like all stainless). The very last item is the CO2 tank and regulator. I use a 20 LB tank which I have outside the fridge to make more room. Only the manifold is inside the fridge. If you are going to share your beer then I would recommend a 10 to 20 LB tank and dual guages so you know if the tank is getting low. If the above seems to be greek language just have the brew supply vendor help you as they have done this many times.

I like these vendors for kegging parts:

I used kegconnection.com and highly recommend them. They have great prices and excellent customer service. They also answered all of the questions I had all the way through the process and was really helpful.
