Wow, this is amazing. Tempted to try one of their $2/month suggestions.

A random provider could be a hit-or-miss. I've personally used RackNerd (found them on LowEndBox/Talk) in the past and can't complain for the price. They have plans under $1/month, and they even provide an IPv4 address:

No affiliation, just a happy customer.
