Digikey.com has stock, CD74HC30 dip. Also I use findchips.com. Really problem is some of these parts are obsolete, not in production anymore.

Be careful of the all-in-one coffee maker with grinder machines. The wet grounds are dumped into the machine's waste bin where they will grow mold and unless you like mold this could be a problem. We have one in the office and this is it's major issue. Yes, we regularly clean out the waste bin but it's always wet and has some grinds left in it.

I vote for LinqPad also. A quick way to check out code snippets, classes and even small programs. Works with C#, F#, SQL and even VB. Similar debug methods as Visual Studio.
