See, the beauty of a limited budget is that you can generally slightly expand it if you progress over time.
That is, it'll take you a little bit to build your first CP--it's not exactly difficult, but there are things to learn. People here will say "it'll all just fall together"--and it does.
Do some research, some homework. Design some CPs graphically, get some feedback. Find something you like and make a cardboard replica.
There's a good chance you can build an even better CP than the X for less--and I would have, but I did some fancy-schmancy upgrades.
It's worth it in the end.
