Anyone use the AC Manifold Gauge Set from Harbor Freight?

I have one. It has worked fine for me the couple of times I've used it, and as you say it's easier to use than the cans with the triggers on them.

Your local AutoZone or NAPA will probably loan you tools if you need them for a one-time repair. I borrowed AutoZone's vacuum pump once when I needed it (had to go to a different AutoZone store than the one closest to me to get a loaner).
