the market window already has a buy quantity button, as does sony's. see my post in the comments on the broker page

as for the "my class/level", the standard broker saved searches would do this just fine.
i've got updated versions of my stuff (including the new effect search of LU42), just have to take out the debugging code/buttons and repackage them and get them up here, i'll try to get that done this weekend.
