Is it worth it?

[DasUrmel]

I agree as well... electricity costs is the main factor (in Germany around €0,23/kWh)...

AND luck !

If you find a block just after a few days of mining with 100MH, everything is ok 

After mining for a month or two with 1GH and not finding one, you might get frustrated...

That's what pools are for.

Is it worth it for people with low hash speeds to bitcoin mine?

I'm thinking if you live somewhere cold, it's definitely worth it during wintertime! That way the electricity you're burning off (probably at a loss) warms your toes.

Just for fun, I have a Mac Pro with its stock GPU cranking away a massive 5 Mh/s... I joined a pool and it looks like after a week I've earned one bitcoin dime! (.01 BTC)

But boy are my toes warm.

Heheh, my rig is so loud, and it literally doubled as a space heater in the winter. A space heater that rose the bill, a trifle sum... 

But I will look into setting up a mining rig (Possibly/probably part-time, given the lack of a hard drive in the system for it to be useful for much more). I also will try and learn a bit more about getting efficient speeds but a slightly more economical footprint. The GPU is looking to be the most important aspect of a mining rig, at this point. I'm now just wondering what I could do after that... But it'll be worth the ride anyways.

Mh to Electric usage is key.  Its almost always worth it to mine or we would not be spending millions to do it.
