Do you know if the IRIS CB-70 rack is any good? I like it because it is only three tubs, heat tape included, and $100 less than a four tube from Boaphiles. Since I only have three BPs I only need the three tub and I emailed Boaphiles but haven't gotten any response what-so-ever whether or not they can make a three tub version. I really want a rack system like this.
