I've had 4 acrylic tanks made for me so far (lol), one from Gen at Kritter, and 3 from SoCalCreations down in San Diego.
Gen is a really nice guy, he'll deliver to your house, drill the holes on the spot, flame polishes the holes, etc. The stuff he builds is really top notch, and despite some claims that he takes awhile, my tank was done in a week!
He isn't very high tech when it comes to 3d modeling stuff, he basically does nice wire-frame CAD like designs for you, which is totally fine and much better than I've experienced getting quotes from other companies.
He did a cool tank for me where the sides and front were one piece, rounding the corners. There was a little edge on one side, but it wasn't bad at all. The weirdest thing is, the eurobracing was a bit uneven. Sure you don't see it, but it definitely wasn't uniform.
My SoCalCreation tanks were all 100% flawless. It looks like they were made by a machine. They use Spartech Polycast for no extra charge usually, which is some of the best acrylic for aquariums from what I've researched and seen. The customer service is amazing. They also make the most beautiful custom stands as well.
They don't send you any wire models etc., but they instead make sure they get all the details. They also go out of their way to make things a bit better. They totally rounded the lip of the tank for me, polished etc., but for Gen's tank, if I didn't tell him, he wouldn't do it, which is fine, but just goes to show SoCalCreations goes far beyond what you expect.
So anyway, I'd recommend Gen, or if you can, get a SoCalCreation tank shipped. Shipping is a bit, but worth it in my opinion. They will also create custom sumps, stands, etc so you can get the whole shebang.
Goodluck!
