I've made synthetic LAB TIFFs of both the "deluxe" targets which you can
convert to the working space of your choice and sample away:

Though really, if you're doing the calibration manually you aren't likely to
gain anything from purchasing a more expensive target; they're really made
to assist profile building software.
