You will hear a whole lof of negative. I have dealt with Tom on numerous occasions, and once I got to know him, no problems. They will build a solid tank (some people have issues with the warranty, though), but customer service is the big area of negativity. If you tell him exactly what you want, you'll get it. The silicone work used to be sloppy (from previous online discussions), but I've got a few glass tanks from him and they aren't too bad. The acrylics I've gotten I wouldn't use for display, but they have worked fine for frag tanks and sumps (I did have one develop a slow leak after about a year and a half). I've been out to the shop and picked up at least 5 tanks from him over the last few years and will continue to buy from him (he'll have to ship next time;)).
