I got the Weinmann DP18 rims w/36 holes & Shimano 2200 hubs for almost nothing at an REI garage sale. It was what looked like a brand new take off, and I can see why. Thought it were perfectly straight when I put it on, it was completely out of true within ~50 miles. I've put maybe 250 miles on it total and have had to true it about 5 times. I do weigh 200 lbs but I thought 36 spokes, even on a lower-end wheel, would be able to handle that.
