If you already have a DV camera, you may be able to use it as the analog input. Most Sony cameras have a software (read: menu) switch that changes the AV plug from Out to In, and then it's just DV into the MacBook via firewire.
If you don't mind looking on eBay, try to find the Sony DA1 or DA2. Those are stand-alone analog->DV adapters. You can sometimes find them for less than $100. posted by tomierna at 9:26 PM on April 26, 2007
Look into Elgato's EyeTV, there are a bunch of different models and they're relatively inexpensive. Bonus? You'll turn your MacBook into a TiVo! My boyfriend has the EyeTV 200 and loves it. posted by Becko at 11:47 PM on April 26, 2007
I asked this exact question five days ago, and I ended going with the ADVC110's bigger brother, the 300. It's sweet.
