I had my glass sump made by them because I needed specific dimensions and didn't want to spend the money. They only made the box and I added all baffles myself. I would say its about the same quality as petco. Very cheap if you want custom but you get what you pay for.
On, fujimoto is a verry cheap company, but... If you are very specific on what you want the only complaint would be messy silicone seams and non beveled edges. If you tell them that you want a tank made with know specifics you will get a tank made out of 1/4" glass with ugly trim and huge oversized bracing. But if you tell them no trim, 1/2" glass with a 3" euro brace with no center cross braces they do a very decent job.
I scored a 60" custom visio with black silicone for 40$ more then a fujimoto at my lfs i almost did the fujimoto but there braces are funky double to triple layer and then i read the online horror stories when i googled them about seams blowin out lol so changed my mind quick
