I actuall just made a dresser all out of 3/4 and 1/2 in MDF... if you are going to paint it, then that is the economical way to go... it cuts good on a router and also will hold a drywall screw ok... i would suggest the self tappers though... i biscut jointed everything and used drywall screws... holds great...However it all would depend on what you are looking to do... raised pandel, shaker, or solid doors???? are you staining or painting? if painting you can use MDF for everything... just rip 1x3's to use for rails and stiles. if you are staining... you will have to bite the bullet and go for poplor, maple, oak, etc.... you can use 1x2 for face frame (if your using) 1x3 for stiles and rails, and if you are doing raised panel... vary the marterials combime 1x3,4,6 etc... biscuit joint them and clamp, then you can run thru router.... hopefully i am accurate and this helps... these are the steps that i have used that have seemed successful... hope it helps...
