Building an even splitter is no big deal for 50 ohms. I have cranked out hundreds over the years. Use a Wilkinson design. FOr two way its two pieces of 75 ohm coax, cut to 1/4 wave with velocity factor, like rg-179 and a 100 ohm resistor across the split ports. You even get a little isolation for all your work. Bandwidth is fair, isolation is better than you would expect and ease of construction is no big deal. There are web pages describing their construction and basics all over the web, like on Microwaves101.com. Heck, I built them for years without even understanding how they work and all of mine did ok.
Or, I can build you one for 30 bucks, includeds the priority mail rate right now, shipped I have built this design from 44 mHz (got kind of big!) to 1500 mHz. My best experience is in the less than one foot of cable class. As you pass 800 mHz the parasitics start to get you. Had excellent luck at 100 mHz a few years ago too. that one carried almost 50 watts at its sum port. My point is, there is no excuse for using a TV splitter anymore!
