I'm not looking to monitor a massive infrastructure: 3 web sites, 2 mail servers (pop,imap,submission port, https

few network points to ping to ensure connectivity throughout my system. Scheduled notification windows (for example, 
during work hours I don't want my phone pinged unless it's everything going offline. Off hours I do. Secondary 
notifications if problem persists to other users, or in the event of many triggers. That sort of thing). Sensitivity 
settings (If web server 1 shows down for 5 min, that's not a big deal. Another one if it doesn't respond to repeated 
queries within 1 minute is a big deal) A Weekly summary of issues would be nice. (especially the 'well it was down 
for a short bit but we didn't notify as per settings')
I don't have a lot of money to throw at this. I DO have detailed internal monitoring of our systems  but sometimes 
that is not entirely useful, due to the fact that there are a few 'single points of failure' within our 
network/notification system, not to mention if the monitor itself goes offline it's not exactly going to be able to 
tell me about it. (and that happened once, right before the mail server decided to stop receiving mail).

Some external monitoring services I could recommend:
