I've found that the CZ often had above average wood hidden under that finish. You can get everything done to your wood far less than building a new one.
Basic wood will cost you $50-100. Shaping is $125-175. Fitting, finish and checker $400 up with the focus on up. If I was going to the expense to build a new stock I wouldn't use cheap wood so in my book add another few $100 to the blank.
