After talking with the lady on the phone, I've come to the conclusion it is a SR4310. I think it has a small freezer compartment on top. I was hoping it would work because it would be nice to have an under-the-counter version in case I finally finish my basement someday and build a bar. The other one I had in mind is a 10 cu ft freezer-on-top model, which is looking better by the minute. Although, if I get one that big, I might as well just hold out for a full-size.
I'll still check out the other one probably, just because it is so cheap. If I can't make it work and I ruin it in the process, no biggie. I've got a pair of tin snips in the garage calling my name.
