Don't forget, your limit on the check is the [Device Rating]. So without teamwork or drone swarm bonus to limit, you're only getting 0.25 electronic parts per Meta Commlink or Printer.
If you have 8 dice for Hardware skill, then printers are the way to go since you get the parts even with the -4 dice. If you're at less than 8 dice, you'll want to stick with items like commlinks for the bonus dice.
Edit: Can't help it... the analyst in me has to:
1 electronic part = 200 (5 for 1,000 discount)
4 x 100n Meta Commlink = 400n for 200n in parts
4 x 25n printers = 100n for 200n in parts.
With a Hardware Tool Kit needed, you'll need to make 5 parts using 20 printers to break even, not including overhead costs and glitches, if you can sell them for book pricing.
