Cheap in a subjective sense for sure. From what im seeing brosing the bst section here, a "cheap" authentic tsuba is around $150-200. By objective means, sure thats not cheap. Subjectively, there are some on here for a few grand. If I just want them complete, I could grab an ebay tsuka ( http://www.ebay.com/itm/331471513906?ssPageName=STRK:MEDWX:IT&_trksid=p3984.m1435.l2649) and modify slightly to sortve fit, and repro $40 ebay tsuba and leave it in the new plastic saya it came in from the antique dealer.
As it stands, im pretty sure that neither of these blades warrant a polish, or any high priced components. It does seem that the style of saya / tsuka shown here - http://www.e-sword.jp/sale/2015/1510_1043syousai.htmis the cheapest restoration option, since it dosnt require wrapping the tsuka or a tsuba at all. Im not sure if the saya could be stained and modified to fit a tsuba and wrapped tsuka later or not, since I personally prefer that look. (I found this guy on here that im tempted to get for one of the blades it if I knew it would fit http://tinypic.com/view.php?pic=znq8ep&s=8#.VN4FvC5jZSC )
