They may suck compared to a proper industrial-grade gauge, but as far as inexpensive automotive-styles gauges go they're better than a lot of the others.
After having been very unimpressed with VDO in the past I decided on a 30" to 15PSI Borg-Warner mechanical boost gauge when I built by current setup. 'Twas worse than the VDO- the needle exhibited lots of stiction and it never went below about 18" of vacuum even at closed-throttle decel at 4,000 RPM. I replaced it with a 30" to 20PSI Autometer Sport-Comp, and it's *much* better. The needle movement is perfectly smooth, it behaves correctly in high-vacuum situations, and my eyeballs say that it tracks my MAP sensor pretty damn closely along the full range.
Specifically, this is the one I have now: http://egauges.com/vdo_ind.asp?Type=...mp&PN=ATM-3301
Very happy with it.
