Strendo - Thanks. Do you have any other fixtures that you would compare it against?
As far as quotes, costs, and service so far for me - here is a short summary.
LeeMar: Didn't get a quote from them because they won't quote directly to the public. When I asked them to suggest a place that could quote me one of their tanks, they said sorry we only work in SoCal, Arizona and Nevada. Their tone was rude and it seemed that they wanted me to feel embarrassed for even asking.
A.G.E.: Also won't quote direct, but responded immediately with just tons of information about their aquariums and what sets them apart. They suggested who I should talk to about getting a tank quoted, options I have, things I may have overlooked, etc. By far the most professional and came across as very prideful and knowledgable of their work. They sent me sample photos of tanks and overflows, worksmanship, and options. I still haven't seen a quote yet, and although I'm expecting it to be pricey - I'm impressed with their service and quality of product.
Miracles: Turned around a quote for me within 2 business days. Price as it turns it is very competitive. Probably the best deal for the money when considering the cost for delivery as well. Unfortunately after the quick turn around on the quote they became difficult to get a hold of, and more than a week passed until they returned any of my calls/emails. When they did get back to me they told me they were shutting down for another 2 weeks. If they would have answered the phones or responded to my emails, they would have long ago had my order.
Glass Cages: They have been by far the easiest to get in touch with and without a doubt the most responsive. Quote was to me within hours of my request, and came out to be the lowest price. Very personable on the phone and really just pleasant to work with. However, their delivery method is that they bring their truck to a local place and you have to go get it from the truck yourself along with everybody else who has an aquarium on the truck. To compare it to the other builders (who will deliver to my door), I requested front door delivery service which they quoted me a ridiculous amount, making this aquarium more expensive than Miracles. One difference though is that this tank would be all 3/4" glass, whereas everyone else has quoted 1/2".
Tenacor: Provided a quote within a day, and talked to them on the phone a few times - really a used car salesman feel to the whole thing. Pricing didn't lookk that good, but also didn't send me running. Unfortunately, the sales guy was trying to screw me and I called him on it. He got awfully shaken and defensive, and then starting rambling on about all of these special charges and justifications of cost. They apparently do some good work, but I'm just not feeling it.
Aquarium Obsessed: The experience has not gone well so far and I am going far out of my way to give them the opportunity. I still have not got a quote out of them and so far it seems that they are completely un-interested in earning my business. We will see.
