What do you have for fixtures, heating and lighting?
I'm guessing that's a glass tank? When you get ready to upgrade, go melamine and it will hold the heat much better.
If you have a 10.0 or better lightbar, make sure it's not obstructed - bare air to dragon if you can - and no further than 1-2 ft away, then you can make any place a basking spot with a ceramic fixture and a heat bulb. Ceramic is important or your bulb will melt it.
Make sure your heating is off to one side so there is a hot/cold gradient in the tank. Go one up on the wattage from whatever your current heat source is - save any old bulbs - you'll eventually need them
For lamps:
Ceramic = area heat, slow to dissipate if there is a power cut. Good on a thermostat and long lasting. Less obvious when they fail.
Red or Blue bulb = good for directional heat, quick to dissipate, pops easily, can explode, bad on thermostat but very high heat output so really needs to be on one, very obvious when they fail
Heat projector = directional + some area, slow to dissipate, higher heat at lower wattage, good on thermostat, but expensive
They all have their uses and I have a couple wattages of each handy - but we also don't have AC here in NZ, so indoor temps can fluctuate.
