"If you have to ask, you're probably not ready" shouldn't be taken with any offense - you shouldn't get a burm without doing research, and that research will let you know if you're ready or not.

Some basic things to consider before buying one:
1) Do you plan on making a serious commitment to this snake for its entire life? Do you have any "life events" such as moving or going away to college or anything like that on the horizon that would cause you to have to get rid of it? Burms are VERY hard to place, many are euthanized every year by shelters because there are no homes for them.
2) Do you have the financial ability to house and feed this animal?
3) Do you have a "buddy" who would be willing to assist during feeding and maintenance?

These are just to name a few. If the answer is not a definitive "yes" to all of these, then the answer is NO, you are NOT ready. Not trying to be discouraging, but its disgusting to see how many of these animals are abandoned time after time by owners that are no longer capable or interested in keeping them.
