Add-Ons with the T8 Animal Plastics Cage

[Bmocken]

So, I'm thinking about getting my very first snake, and my friend recommended that I buy a terrarium from Animal Plastics. I saw some people on this and other sites who seemed pretty happy with these terrariums so I figured it'd work out well. But, looking on the site there is a list of add-ons I could get with the terrarium, including locks and Flexwatt belly heat. Is the Flexwatt better than buying a UTH from a different place, and are the locks necessary?

I just ordered a T8 and the only option I got was the lock. You can get flexwatt from other places probably less expensive. Just keep in mind Quick ship takes 3 weeks before it leaves their warehouse so plan accordingly.
