If you don't mind sharing, what did the refrigerated unit cost? I know it's all about timing to get the right deal, but I've seen them on EBay for anywhere from $500 up.
I still have the ice bin, and yes we have to fill it up pretty much every day (meaning it never gets below halfway empty). I got a sweet deal on a self contained Manitowoc ice maker (QY214) on Craigslist from someone going out of business, so that makes it somewhat easier. I don't have the ceiling height where the soda machine is to have an ice maker sitting on top. Plus now I have ice any time I need to have a cooler filled up!
