The cable and fucntionality are almost a non-issue. Cables can be made from SDL connectors (about $5 each) or purchaed from unicomp or eBay (roughly $25). As long as the membranes still work, a new controller can be installed (for pretty cheap actually! check out soarer's controller code running on a arduino pro micro. The only undetermined part at this point is the connectors) etc etc.
The other thing that I find offputting is the low-quality purple printing lexmark has used on this model. Of all the buckling spring keycap printing techniques, this is my least favorite, closely followed by "yellow halo: PC model F keycaps.
still, it's an SSK: already up over $100
