Nice! I'm about three hours north of lawton. IDK about the tank though, I saw a 300 for sale here a little while ago cheap but it was snapped up before I could get it. Thats the only one I've seen, this isn't really a good area for MONSTER fish keepers. sad thing is, the guy used it as a tank for little marines like damsels and whatnot (fail.).
You could probably make one of those look nice with furniture or a big box around the gaudy blue colour.
So thats my experience.
Although, If your'e looking for many smaller tanks, Like three or four stacked 125's for real cheap, theres a store goin out of business here-- I'm getting people together to make them an offer on their fish room. 125's and 150's are the biggest tanks they have, but theres lots of them, PM me if you're interested and I'll get u my phone #.
Sorry I couldn't be more help.
But yeah
I'm down for the texas/oklahoma fish club
