Option 3 would be: Getting one made. This was what I had chosen, as where we live such enclosures cannot be bought (there was only a smaller ExoTerra, sold for converted to USD a hefty 600! imported things are very expensive here), and I also wasn't able to build one as we were recently moving (means: no leftover parts from another project, tools still underway, and cutting and assembling all the parts in an apartment also hadn't looked optimal).
I had then tried looking into whether I might be able to find a used very large fish tank. Also wasn't available.
Looked whether certain furniture could be repurposed (especially glass cabinet "IKEA Fabrikör" can easily be repurposed into a vivarium, enclosure...) - a bit too small for a dragon IMHO, would have been very nice for a bit smaller reptiles but I just wasn't into getting anoles or a chameleon.
I then opted for: Glass tank made by a glass company, and I make only the lid (wooden frame, hinges, wide-hole wire mesh). Worked out fine for a very reasonable price (converted to USD only 200 USD, but custom-made things aren't very expensive here) and I'm very satisfied with that (my dragon Taco is also

). This way I got a 120 cm x 80 cm x 80 cm (200 gallon) tank. I first had thought custom-made will be extremely expensive so I had not considered first; the idea came from my husband who sometimes had custom-made aquariums and said I should try asking around glass companies.
Under a bit different circumstances I might have opted for buying an enclosure (especially one that can assembled like furniture at home), or building the complete enclosure and not only the lid (maybe even from repurposed furniture). Good that there are quite a lot of options to chose from
