+1 bonus to 4 physical stats for $140,000 and 0.70 essence. (Agility, Strength, Reaction, Body)
Muscle Toner $32,000 and 0.2 (agility)
Muscle Aug $31,000 and 0.2 (Strength)
Bone density $5,000 and 0.3 (body)
*********************************
$68,000 and 0.70 essence for 3 stats in basic bioware. There is nothing in the basic ware for Reaction, which means you have to jump to cultured ware.
Which would be the synaptic booster.
$95,000 and 0.5 essence for +1 reaction (AND +1 initiative dice as well).
Which means a total of 1.2 essence and $163,000 spent. but you would also gain +1 initiative dice; and lock you out of wired Reflexes and Reaction enhancers.
So, its not a bad piece of tech for what it gives you and what it can save you in terms of essence. (Remember the +4 cap to stats)
