I while ago there was a thread on having a 20 gal contest that never ended up really going anywhere. But the "point" idea I think is a good one.
This allows for the guy that wants to spend silly but acutally has a nice tank to be compared to the guy who does nice DIY work on the cheap. As well, it removes the need to be so "a&^ retentive" about the budget, and not argue about the details.
I'm interesed in joining in, as I would love to build a 20gal just for the heck of it. And the "get more point for being cheaper" allows for me to post up MY cost out of pocket using my extra equipment, frags and scraps kicking around from my 220, and a guess at what all the materials would actually be worth to by.
IE, more fun and less mindless bickering.
PS. finally something to use my old prism skimmer for.

For some reason it just doesn't seem to cut it on my 220 gal
