The following assume that you don't spend more than half your WBL on a single mecha. Since the standard mechs cost is 100% of the WBL for a character of its CR, this actually works out nicely, and you can buy something of your CR if you really want to, but it'll break your bank. If you're building one yourself, you can also get away with something of your level quite nicely. For your average joe, mechs are supposed to be somewhat overpriced.
Note: Some mechs may cost more or less than the indicated value by CR. These numbers are only supposed to serve as a baseline.

... I'm starting to think this whole "base things on WBL" idea is a bad idea.
