Riddle Me This

Well, since I like to give away prizes, I`m going to ask a series of questions over the next little while about GC, until I get bored, or run out of questions to ask. The questions will be weighted in a way only I know how, not all will be worth the same :P

The winner will be awarded 10 minor gordos, and 10 regalos, with 5 and 5 going to the second place person. This might go up, I just don`t have too many gordos at the moment :P


First Question: Which A-miner ship has the best PR/Upkeep ratio (not including the starbases or neutral ships)
