drilled vs. hang on overflow

[turtleman9100]

Although I know this is a preference but, I set up my 125 non drilled tank last week. Everything is finally settling down. Now I got the chance to buy a drilled 135 with 2 built in overflows for $200.00. If it were you, would you tear down the 125 non drilled which is running perfect to upgrade 10 gallons more with built in overflows? Its a lot of work. Please give me your opinion.

The built in overflow is nice but personally, I am not sure I would go through all the trouble for 10g. What kind of external overflow are you using now? I would also compare the dimensions of the two tanks.
