You only need a moogle kit if you want to use original cherry, wyse, or dolch ds sets from donor boards that have odd layouts or off center stemmed caps.
Most group buy sets (like Red Alert or CCnG) should have all the keys necessary for a Poker. Pretty much any 87/104 set of caps like from ebay/feng/qtan/imsto should have all the keys necessary. A Poker is basically just the num row/alpha section off of a TKL, aka a TKL minus the Esc row, Insert-Home-PgUP 6pack, and arrow keys.
