Either are going to require plumbing.
My HOB overflow cost about $80.00. And has broke syphon a time or two.
I don't know how much to pay for the actual drilling but that would be better for reliability. Still can plug but at least there is no possibility the overflow itself would break syphon.
HTH
Get it drilled and save yourself the hassle. Is it a glass tank? You can buy all the parts (Dremel tool, two bits) to drill it yourself for around $50. Pricey but if you ever want to drill a hole again it's free. And it's easy to do too. Places around here charge $25 per hole.
Does it actually have an overflow box (made of acrylic) around the hole? That will up the price at least another $40 as well.
If you could show a photo of what you're asking for specifically I could tell you what you should expect to pay to have it done professionally.

Waste of money. Just buy a Dremel and you can cut circles, squares, or star shaped holes if you like. You're also not restricted to any size hole.
Thanks for the responses. Its a new glass tank,not tempered. I want to get it drilled and have an overflow box installed. The LFS wants $150 to drill,install overflow, bulkheads, etc. I thought this was kinda high but it might be worth it after all. If I drilled it myself I might muck it all up. Im building the stand and canopy so at least Im saving some $ there.

Part 7103 and 7134. Diamond tipped bits. Part 7103 (the one with the ball at the end) is used to make the initial hole. Make sure to make a tiny circular motion when doing it. Then use the other bit to "saw" a hole in whatever shape you like. Use a ton of water at all times. I just let a garden hose trickle onto where I'm cutting. Go with the highest speed. And practice before you do it on your tank! I have never cracked the glass and I've drilled 9 or 10 holes.
The only real complication with an overflow box is if the siphon breaks you have a flood problem (for starters). But, a simple float switch can prevent any real flooding problems. I have had tanks drilled at my LFS but you have to be willing to accept the risk of the glass breaking whoeever does the drilling. The best solution is just to buy an already drilled (reef-ready) tank.
