Pretty expensive grill! 30.00 plus the cost of the kit around 80.00 - yikes! Not sure the cost is worth it, as with the top on will you really notice the "see throughness" of the inner grill, not to mention being covered with the outer protective armour grill. Voyager have somewhat diseptively not included the radiator parts from Step 15 to their example. I wonder how much the grill would add with this in place, probably just be a dark nothing. The control rods don't seem to be an upgrade as PE is flat and those things should be round. Not sure if the side "fenders" add much compared to the kit parts. Same for external protective grill, is it really a needed "upgrade" from the kit part? The kit does not include injection tubing but i think scratch built from brass wire would be a more accurate solution than these 2 dimensional parts provided in this PE fret. I like the small metal box though.
