I'd say that's a pretty good/decent/average price.  You could get a quote from two or three LFS's and compare.  I have found that they are generally competitive based on manufacturer, size, design elements (overflows, holes, etc.).  Remember that there is not much mark-up on tanks/stands.    The LFS's make the majority of their profits off of livestock and dry goods, not tanks.
HTH
p.s. I'm not an acrylic "expert" as my last/current three tanks are 
       glass, so I may stand corrected.
