I will say personally that I had a fantastic customer service experience with Animal Plastics. Got two T8s with locks, Pro-Heat RHP installed, LED channel cut for my own light strip, and they were an absolute breeze to assemble. Detailed instructions but no-brainer assembly. I've also heard from other folks here that they'll overnight or at least ship the same day for damaged parts.
They did take about 7 weeks instead of the 3-4 they told me but then offered $45 credit for my next order. Needless to say, that $45 is buying me a shelf in whatever size cage I order for my SD retic next. AP has my business for sure. I'm actually going to ask about a couple custom mods to the next cage if they can cut the pieces I'm thinking about.
So yeah, setting up a tub while you wait for a PVC enclosure would probably be the most upfront initially but be the best investment in the long run. I will also say that as a long time glass enclosure and Neodesha Plastics cage user, AP or a comparable set up is far far better.
