If you are going to get the tank I'd suggest a 20 gallon long. You will need a UTH for it on one side, a thermostat for the UTH (you can find decent cheap ones online) or a rheostat. Two identical hides, one for each side, a water dish, and then decorate as you like. I also use black Con-tact paper to cover the back and sides of the tank...helps them feel more secure. You will also need to cover about 2/3 of the top of the screen top to hold in humidity and heat better. You can probably get all of that for under $100 if you shop wisely. A digital thermometer at the very least with probes to measure temps.
