The NOAA charts are fine for a lot less money, but you do have to be
careful with Notams - but even with current jepp charts you probably
should do that anyway.

The NOAA charts sometimes lack convenience features. If you land at
KIGQ the chart says use the KMDW altimeter setting, but doesn't provide
the KMDW ATIS freq - you have to turn to another page to get that.

Forecast weather - I like http://adds.aviationweather.gov/ a lot. For
local airports, I use

I still like to talk with FSS just before takeoff to get their take on
inflight weather.

For inflight weather, you can't beat the new XM systems, and a
stormscope on top of that gives you a great view if it's nasty.
