Product review (4 stars): Good Starter Kegorator
This has served us well for years.  It's attractive enough to be kept in a public space- way nicer than a conversion kit. It was still in great working order when we retired it (new baby meant using the space for a pack and play).  The cooler does come with shelving so that it can be used as a mini fridge (but if you wanted a mini fridge, you'd just buy a mini fridge.)  My husband's buddies were in awe of his beer dispenser and we started a trend around the neighborhood of having these in garages, basements, and home offices.

I bought this for my husband for Christmas.  I'm not huge into beer, but it seemed like a pretty good value.  The cost of the 1/2 keg varies from about $75 to $120 depending on brand and distributor.  Be prepared to shell out a between $50 and $100 for the original keg, but for future purchases you will exchange your keg so it's kind of a rolling deposit.  A 1/2 keg is about 7.75 gallons or equivalent to about 3.5 24-can cases.  We found it to be slightly cheaper to use the keg than beer in cans- and it tastes better!

It is a pain in the butt to haul a keg into the house, but you probably knew that when you started shopping for a kegorator.  We bought a dolly for hauling the keg from the car to the house.  A dolly is a nice thing to have, anyway. I like that this kegorator has a sliding plastic board (is there such thing as a plastic board?) at the bottom that makes it relatively easy to get the full keg into the cooler.  It's easily a 1-person job.

Sadly, it's not perfect.  We started having problems with the regulator leaking after about 6 months and had to replace it.  Also, there's only enough space for a 3 1/2-lb CO2 tank inside the cooler.  There isn't really a nice way to keep the tank outside to prepare for regular trips to the store.  You can get these tanks filled most places where they fill paint ball canisters (like sporting goods stores) or at industrial gas shops.  They look at you a little funny with your 3 1/2-lb tank, but it's cheaper than the sporting goods stores.
