Esopps 800 overflow or get tank drilled?

[Bugsy_Barboza]

Debating on buying a eshopps overflow but don't know which way is the safest from having a flood... Or should I just get my tank drilled?

Getting it drilled is definitely safer. Pretty easy to do it yourself also, check out glass holes.com

Mine flooded. Then I replaced the tank with one I drilled.
