Can I get some help making a shopping list for an enclosure for my first snake? I'm planning to get a gopher snake but that may not pan out because of space, in which case I'll likely be getting a corn. I'd like to get a PVC cage from Herp Houses, and they said they can help install accessories if I bring them when I come to pick up the cage. This being my very first time with reptiles, I'm still uncertain what specific products I should get. It'd be great if anyone with colubrid experience can help me out with this?

So I do know that I need:

- an RHP - I have no idea what wattage/size to get for a gopher or corn. I guess it's hard to determine at this point, when I'm not 100% sure what size cage I'm getting.
- some form of under tank heating - am I understanding correctly that Flexwatt is the common method for PVC cages?
- thermostat - for a North American colubrid, would a simpler one that's not a Herpstat be sufficient?
- lights - what's everyone's preferred way of lighting PVC cages? So far I've read that you can just glue or silicone LED strips on.

Am I forgetting anything?

Also, I'm still having trouble with exactly what size cage I should get, if I go for the corn. Herp Houses offers 24x24x12, 24x24x16, 48x24x12 and 48x24x16. Would a corn require one of the larger ones? I'm frustrated that there doesn't seem to be a 36' cage available from Canadian companies. Honestly if the cage size gives me problems I might end up going for an even smaller snake, like the hognose...
