Just to follow up:

After much research, my conclusion is that I will: stick with X10.

Yeah, their products are cheaply made, and the powerline communication is easily interfered, but so far every other solution is a massive leap in price. Seriously, it's little ridiculous. I can get an X10 wall switch for $9, whereas with every other solution I've seen I'd have to spring for at least $59. That's just too much when we're talking about 9 switches in my two-bedroom apartment (I have more than nine switches - those are the X10 ones).

In case anyone is interested in getting into X10, it's actually surprisingly cheap to do so. I go through an ebay store that has strangely low prices and free shipping on all products. Most of the stuff there goes for 1/3 of X10's list price.

I outfitted my entire home (okay, about 4/5ths of my home) for around $250. That includes the nine switches (that includes 3-way switches), about 12 lamp modules, six remote pads, four wall remotes, a regular receiver/transmitter, and a computer-programmable receiver/transmitter. I might be forgetting a few other things, but that's pretty much everything I use. To outfit myself with this stuff using any other types of products it appears it would cost me upwards of $2000!
