hey guys, not strictly cnc and i'm sorry for that but i'm sure you guys will know the answer.

i'm looking to make a 24" tv slide in and out of a housing i am making. so first place i looked was at round rails but the price seems a bit high for what is going to be a cheap gimick.

can anyone think of something to use for linear motion that will happily hold a flat screen tv when extended and it not wobble all over the place?

preferably within a budget of £50. rough sizes of the rails would have been 800mm to give you an idea with around 400mm spacing between the bearings
