I use the 7001DX and just love it. Weighs perfectly, has a hold feature which is very handy when you are trying to control a busy snake and not lose that weight reading and hardly goes through any batteries.

You can find it here....

Having used Reptile Basics tons of times, personally I'd recommend them.
