I think that there is room for better quality vehicles (including spacecraft) and I suggest the following modifications. Cheap components would inflict a -1 to skill to operate, +1 skill to repair, and would have a CF of 0.6. Good components would give a +1 to skill to operate, -1 skill to repair, and would have a CF of 4.0. Fine components would gives a +2 to skill to operate, -2 skill to repair, and would have a CF of 19.0. Best components would give a +(TL/2, rounded down) to skill to operate, -(TL/2, rounded down) to repair, and would have a minimum CF of 99.0 (if it is available at all). Repair costs would be modified by the CF of the quality of the component.

Instead of modifying skill, Cheap Armor would have -20% DR, Good Armor would have +20% DR, Fine Armor would have +40% DR, and Best Armor would have (+[TL/2, rounded down] * 20%) DR. Force Shields would receive a similar modification while Defensive ECM would modify the penalty to the enemy and the dodge bonus (rounded down).

So, in the case of a TL10 SM+8 streamlined spacecraft, it could purchase Cheap Nanocomposite Armor for $4M per component and receive only DR 15 per component, Good Nanocomposite Armor for $25M per component and receive DR 18 per component, Fine Nanocomposite Armor for $100M per component and receive DR 21 per component, or Best Nanocomposite Armor for $500M per component and receive DR 30 per component. Of course, only experimental spacecraft would probably benefit from Best Quality components.
