I see new ones for $50-$60 but I only forsee ever using it for 1 hole.
Other options could be use acrylic(but bonds poor to glass with silicone) or have a go with the waterjet table at work but it etches the glass and makes it real hard to clean algae off of it.

Have you tried any local glass shops?
Without a tripod your going to have a really hard time trying to drill through. I just drilled one of my tanks with my dad and we used a toothless bit and silicone carbide with diamond dust in it. Might work out cheaper if u can just find a glass shop to do it for you.
