I actually started doing playthroughs not too long ago. I'm currently playing through Sonic Adventure DX. I have a mostly finished Super Mario Sunshine playthrough, though there's still a couple of videos for it that need to be uploaded. Those I'll be getting up within probably the next two weeks.

I have come to the conclusion that Lets Playing would be a pretty damn expensive hobby! At least to first get started.
Not entirely. All the equipment I use for mine were only about $85 total. A good capture card only costs about $50. My headset was only $20 and I spent around $15 for the av splitters. Together at once, it may seem like a lot, but if you buy them separately over time it's not much.
