I'm not sure if this has been pointed out or how people feel about this. But there is always second hand equipment. For our bearded dragon we paid £40 for the viv, obviously disinfected it first. I know that in my area, the local reptile rescue/rehoming centre currently has a huge issue with bearded dragons. I think they have something like 21 that need rehoming and they are always on hand for advice (good advice). We got ours from here and he has his own story! I also know that Gumtree (again locally) always seems to have people selling baby bearded dragons or complete setup with animals for cheaper than £250 just another avenue to think about.
Again this does depend on how you feel about rehoming. I'm personally all for it as long as the animal is healthy. Actually it's how I got all my animals.
