I know I've been a broken record on this lately, but have you considered not using miniatures?
Miniatures came to the forefront as the borders between war gaming and role playing games was much more blurred than they are now. So much so that the most recent edition of DnD makes playing without miniatures impossible. But what miniatures do is give your players and you a perfect sense of what is happening in every inch of the map at all times. It helps calculate range penalties and keep track of who has taken the most hits. It has it's uses, but do you really need it in a game like Shadowrun?
Even in combat, the player doesn't know where everything is on the board. It's the fog of war which causes them to forget who took a hit how many bullets last go. They forget who is 15 meters away and who is 14 meters away. It reduces the role of the player to a soldier and not a general, something miniatures were supposed to emulate. To give every player complete mastery over the field of combat turns Shadowrun into a game of tactics and dice, something it was never meant to be.
Foregoing miniatures also keeps the player engaged. With a board and pewter, inbetween turns the player can mess around on their phone, look up stats in a book, go get something to eat, etc. When their turn comes around, a few minor questions brings them up to speed on all they need to know, the numbers. This is how a general conducts a war, not how a soldier fights it. While this can not only be frustrating to a GM who spent hours developing this world, it mean your player reduces his character to resources to be spent, rather than a flesh and blood metahuman in a fight for his life. When he is shot, he acts as if he has lost a resources, X number of Health boxes. The same reaction as if he lost a certain amount of ammo or a Spirit service, rather than behaving as if he were fraggin' shot.
To go without miniatures forces the player to pay attention to the world you created, knowing that missing a detail is missing an edge in combat. Again, how a soldier fights. Relying on only himself and his squad to convey info. This makes for a more memorable and engaging conflict that will be remembered as "That time we fought for our lives..." rather than "That time we beat the mission."
I could go on all day about the mechanical and associative disconnect created by miniatures, but ask why they are even necessary before bogging yourself down financially with them. Try a few games with nothing more than a rough pencil sketch of the area. I think you'll find that in a system like Shadowrun, working without miniatures isn't just applicable, it turns the whole game around.
Save your money.
