I picked up a Univega Custom Maxima today from CL. It looks like it's a pretty low end bike with "Light High Tension Steel Tubing" and steel Araya rims. Surprisingly it is in very good shape. The only scratches were on the top tube where it looked like it leaned against something in shed or garage for years. It even still has both Univega Grand Touring tires with all the tread still on them. There is some surface rust on the little chrome bits. The bike has zero braze-ons for shifters, bottles, even the cable guides near the bottom bracket are clamp-ons. It's pretty heavy, but should polish up nice. Here are a couple of photos.

The whole thing cost me $28.
