In over 25 years of aquarium keeping I have had this happen exactly once and it was from a frayed wire on a used piece of equipment that I had not checked first. YMMV but this is not a major risk, and using GFCI circuits, drip loops and avoiding the cable monster should be all the electrical risk mitigation you need.

Suggestions?

Do you ever plan to control your pumps/skimmer/total system? If so, then start with the purchasing that equipment, as trading up with cost from 2 to 3 times in the end. Having said that, I agree that the eheim 1292 is the best base choice. Not the most silent, but reliable and does not have the close tolerances some of the newer, higher performance (more expensive) ones do. Another good choice in the same cost range Sicce Syncra Silent 5, or stepping up to controllable pumps in the same cost range in Canada, a Reef Octopus VarioS-6 or Waveline DC6000

A powerhead with a foam intake guard will do a lot better at oxygenation (flow) than any air pump and stone.
