The only two Nikon lenses I have ever had a problem with were the 35mm series E which fell apart, and the 18-70 DX kit lens that came with a D70 I purchased.
I have a 28mm/2.8 series E that has been though a lot and has held up - bought it used, didn't look like it had been used much when I did, though it isn't built as well as the Nikkors. If you plan on beating them mercilessly, they won't hold up like current AF from Nikon. I got it for under $75, and I really needed a wide angle immediately at the time so it was hard to pass up - served me well over the years.
