Anyone had a plastic holding tank fabricated lately? I was quoted $1,200

Ye gods...who tried to hold you up for that price???

Ronco Plastics makes top quality thick walled rotomolded polyethylene
tanks for a very reasonable price and has more than 400 shapes and
sizes, over 100 of which are non-rectangular...and they install fittings
in the sizes and locations specified by the customer when they make the
tank.

Ronco does NOT fabricate custom tanks, however...they don't make welded
tanks, only the rotomolded tanks for they have molds...and the cost of
making a mold for a one-off would be prohibitive. If they don't have a
mold that suits you, there are two companies who do make custom welded
tanks for a reasonable price:

They both use polypropylene instead of PE, which is fine for water or
waste holding.
