THe tool house carries them also, for about $17.00
Just remember to brase the backside of the area that you are drilling it will make the difference and don't force it let the wieght of the drill do the work.

hole saws
 

you can buy a set of 10(2 3/8-1/4) at summit tools for about 70 dollars

I'm a DIY kind of guy. I build my own hardwood furniture, do my own acrylic fabrication, wire houshold ( and commercial ) electrical and do plumbing. I grew up with tools in my hands (got my first toolkit at 4 years old), built my first few computers, do all of my own car repairs, etc. etc.

SO... I was all intent on drilling my own tank, and I did all of the appropriate research, BUT, I got someone else to do it for me.

The reason? I needed 2 holes each, of 2 different sizes, so expected to pay $40 for 2 glass holesaws (cheap ones), but I was able to get James at Lions Gate Glass to drill the holes at $10 each...
(If you live around the Vancouver area this is a practical option)

BTW the LFS quoted $30 per hole vs. Lions Gate Glass at $10 per hole...
same cost as just buying cheap holesaws, professional glazier working with quality tools, lower risk.

No brainer

bits
 

The best place to purchase bits is CRL. My Company has used there products
for many years. Make sure you follow directions. They also sell steel bits. You
make a small dam and fill it full of aluminum oxide and water. Good Luck. Don

I got mine from Progressive Reef http://www.progressivereef.com/
