I just converted an igloo 4.6 mini fridge into a kegerator. It was $97 on walmart free shipping. I thought that was a good deal for a new mini fridge. Fyi there is a coolant line running through the middle of the top of the fridge. It was real easy to find cut a little hole in the inside, chip away some of the insulation and there it is. No other collant line found, and I was able to drill the holes with no problem. It can fit two corny kegs with very little work you just have to cut out the shelf holders, and remove all the door storage. I didnt have to touch the temperature contoll. Very easy conversion. Thought I would share. Also got the dual tap tower for $87 from beverage factory after shipping it was around $108.
