Benifit to acrylic sump?

[banditpowdercoat]

I may be just over thinking this whole thing, but I need a new sump. Mine is to tall and cant put a skimmer in it or access it well. Now, I have made a few sumps with glass tanks. But, why do people make them form acrylic? It seems like it s more time consuming to cut, route and weld? Is it that much cheaper for acrylic than glass? I havn't priced it out here.
I am just not sure if I should buy a router table and build a acrylic sump, or look for a 30g tank and convert it??
