Move-by-Wire integrates Wired Reflexes with Skillwires, it's one of the very first "package" deals in 'ware.
Yanno, I remember SR3's Move-by-Wire being way overrated, but they seem to have fixed that some in SR4.
'Ware | Essence | k¥ | Effect |
Move-by-Wire | 2/3/5 | 50/85/175 | Adds +2 Rea/+1 Dodge/+1 IP per Rating, confers Skillwires Rating 2/4/5. |
Skillwires | Rating x 0.2 | Rating x 2 | May load up to Rating x 2 Activesofts with Rating <= Skillwires' Rating |
Wired Reflexes | 2/3/5 | 11/32/100 | Adds +1 Rea/+1 IP per Rating |
So Move-by-Wire 3 saves 1 essence and costs 65k¥ for +3 Rea, +3 Dodge over Wired 3 + Skillwires 5, though the increased Availability Rating may eat up much of the ¥ savings.
During character creation, without spending on the Restricted Gear Quality, the best you can do is
'Ware | Essence | k¥ | Bonus |
MBW 1 | 2 | 50 | +2 Rea, +1 Dodge, +1 IP Skillwires 2 |
Wired 2 and Skillwires 3 | 3.6 | 38 | +2 Rea, +2 IP, Skillwires 3 |
So 12k¥ (2-3 BP), +1 IP, and +1 Skillwires vs. 1.6 Essence and +1 Dodge.
I'd go with Wired and then later upgrade to MBW, though it depends on how tight your BP are.
