Hi, I just started riding bikes a week and a half ago. Right now I have a Schwinn mountain bike I bought from someone for $75, but I am looking to get a road bike. I have a very limited budget so I am looking for a starter bike at $100 or less. The mountain bike is great but on the road it just feels like I can't go that fast. I saw these 2 road bikes on craigslist, but from what I am reading they aren't worth it.

I also went to my local salvation army and saw an old Spalding Blade for $55
Are any of these bikes worth it?
