Electric is the way to go... but there is a lot LOT of expense getting it going. (A "lot" is relative, of course... it was a lot to me!)
I started with a 120v system... a High Gravity 120v 10 gallon kettle, that uses the Blichmann boilcoil... 2200 w, needs a 20A circuit. That was the most cost-effective way to get going. Just "plug and play" for me. And I thought the system was great. The power was (to my recollection) adequate to heat the water/wort just about as fast as propane. If slower, it was only slightly slower. And the precision control is WONDERFUL. Even if it was 25% slower, it would be worth it. If I were only doing 5-6 gallon batches, that 120v system would have been all that I needed.
(In fact, lol... I'm pretty sure I'm the guy that sold the system to brew703, who responded above.)
I upgraded because I usually do 10 gal batches (and am now moving to 15), so it had to be 240v. But brewing on the 120V system is what "hooked" me to electric, and for 5 gal batches, it would have been just great.
I already some advantages going to 240v, as there was previously a hot tub at my house... but there was no longer. So, I had an unused 50A breaker in my panel. I swapped it out for a 30A GFCI... and that breaker alone was $100ish. Another advantage: Had a friend who is a licensed electrician. Those happy coincidences were part of my justification for going to 240v. If it would have cos tme $400-500 just to get the power in... I'm not sure I would have taken the leap.
SO, I got started, with a lot of dumb luck, and saved on some of the up-front costs. A power controller (Blichmann Brewcommander) and lots of extras later, and I absolutely love electric, but am easily $1000 poorer. However, I'm happily running in my basement, year-round (with a steam condenser unit).
SO... if you're getting set for a basement remodel, that's a perfect time.
You won't regret electric if you're willing to spend the money. But it ain't cheap.
Also: The pot can be used for both propane/electric if you get one with the element in a 1.5" triclamp that can be removed. (A common electric setup... probably the most common.) You also would need a cheap 'plug' for your thermoprobe (which you'd remove as well). Neither of those are much hassle, and all the bits and pieces can be found at brewhardware.com and other vendors. Frankly, however, if you keep your eye out for used gear... just keep an eye out for 2nd kettle. By the time you get done buying all the other stuff for electric... a used basic kettle for $50-75 will seem trivial!
And I am not worried about getting shocked... at all. The GFCI is your safety net, and simply ensuring things are set up logically seems to make all of this reasonably safe.
