Someone give me that final push!!!

[Son Of Skyline]

Ok...so here I have a very nice used 125gal (48x24x24) with a nice birch cabinet stand and matching canopy, just waiting for me to give the word so we can start building an acrylic overflow and have it delivered to my place. I would be upgrading from a puny 27gal.

At first I was all pysched up as the 125 is pretty much my dream tank (besides the 175gal bow) but as decision time comes near I'm getting more and more nervous.

"Is it too big?"
"Should I spend the money on my car?"
"How am I gonna clean this thing?"

I did run (and still have) a 135gal before, but I found it too big and I don't care for its dimensions.

I really want this tank but I need someone to reassure me that caring for a 125gal isn't that much harder than my 27gal, and to give me some rewarding testimonies of keeping big tanks to give me that final nudge...Anybody?
