Parson's do pop up on the market ocassionally. If you can provide a large enclosure/fre range type of setup and have plenty of time (work fulltime from home here.) to really manage them, and if you are familiar with the needs of chameleon speices then they are a good speciment to invest in.
When Parsons are available their prices are pretty steep to discourage impulse buys. You really need to evaluate your lifestyle habits and ability to care for these creatures before you buy them.
BTW, cute PUG! I have two French Bulldogs!
