I'm with Carol on this. You get what you pay for in this area.
You still need to be choosy though as there are some more expensive solutions out there that don't deliver. e.g. While Sonic basically defines the DVD authoring standard (solutions start at $25,000 and go up to around $100,000 - or used to anyways), their consumer level DVD authoring tools don't quite measure up (or at least they didn't last I checked) and you're better off getting the DVD authoring software from MediaChance, which is cheaper and better.
But if you're just doing stuff for home, it doesn't matter all that much.
Vegas and Premiere are very good and still affordable, all things considered. Many NLE packages can run you into the 10's of thousands of dollars.
Consider that if you're doing stuff for DVD, a Dolby Digital encoder will cost you $1,000, a DTS can be had for about the same, and an MLP costs $2,500. And that's just for the audio encoder. $100 for a video editor is pretty darn cheap all of a sudden.
