do it your slef its the easiest thing in the world, ive done it completely drunk free hand lol its really very easy
15-20$ for a bit from princess auto and the use of a garden hose and drill for 30 seconds and your done.
ive cut full sheets of glass through a wet saw , the thicker the glass the easier it is to cut same with drilling.
lots of videos showing you how on youtube, basically its all the same in the end.
good learning experience and a feeling of self acomplishment knowing you did it yourself.
use the extra money on nice corals or fish
