Hey there Jay! I've attached a link to the relevant Molex catalogue below which lists the product families for the pin spacing in the printrboard connectors. The connectors on my LC are either from another family line, or more likely, molex knockoffs which are generally easy to find in most electronics (it is always cheaper to buy the chinese alternative). I'm looking at getting the following components but I won't be able to state if they are the correct ones until I've tried them. As with most components, if you don't know EXACTLY what it is you need and remember every intricacy of the part code, you might get something just a litttttttle bit different from what you want. I am actually specifying gold plated pins which are only a little more expensive but increase the rated number of connect/disconnect events from 25 to 100 before failures began to occur. Generally you should only use tin if you are connecting these things once and then never touching them again (ex: consumer electronics/toys) and know for certain that the envrionment they will be used in is clean and not harsh (ex: used near salty shores, used in excessively wet envrionments, used in atmospheres with high levels of particulates).

22-29-2031 (Male PCB header, 3 pin)
22-29-2041 (Male PCB header, 4 pin)
22-01-2025 (Female crimp terminal housing, 2 pin) (The catalogue shows a picture of a connector without polarizing ribs, but the website online does! We will find out if they are the right ones when they arrive...this is the reason I hate ordering components)
22-01-2035 (Female crimp terminal housing, 3 pin)
22-01-2045 (Female crimp terminal housing, 4 pin)
50-57-9004 (Female crimp terminal housing, non-polarized, 4pin)
08-56-0109 (Housing crimp terminals for 22-30awg wire)
Like I said, I'll tell be sure to post the results once the parts get here. I ordered a dozen or so of each connector and a handful of pins.
As for the crimper, there are ratcheting and non-ratcheting crimp tools. The price difference is massive, but so is the ease of crimping. This is one of those things that I must sadly say, going cheap will only cause regret. (
