Hi! Dobby is 1 year old now, and big enough to upgrade to a new tank. He has been in a 20L for his whole life, and I have heard that a 40 is the right size to upgrade to. Any recommendations on what tank to get?
I'd go larger if you can. The 40 breeder is really a minimum and I'd only use that if he gets a lot of time outside of the tank. Shoot for something that's at least 4'x2'x2'. That can be difficult to find unless you get into custom builds which can be expensive (especially shipping). If you can, your best bet might be to build one. Here is a walkthrough of a popular model https://beardies.dreamwidth.org/2145.html

I have the same issue. I picked up one of these http://www.exo-terra.com/en/products/natural_terrarium_large.php but it was fairly expensive (around $350 as I recall). I'd go with the Large/Tall or Large /X-Tall version if you can find it. Another good alternative would be to look into having a custom enclosure built. Several places like KMDragons offer this http://www.kmdragons.com/equipement
take a look around sale sites like craigslist or places like that.. you may have to drive a little bit but i've found a few cages, both custom and name brand, that are relatively cheap. if you have the plans for a custom cage and present it to a hardware store they will usually help you out by cutting wood and pre-drilling some materials for you, just need to call around.
