Just an update for myself, I've found some bundles to help me out:
- EAS (Environmental Audio System): http://www.whitearmor.net/forum/topic/25695-environmental-audio-system-hear-outside-your-helmet/it's the ear amplifiers so you can hear outside your bucket. The bundle is $70, a little more than if you do it yourself, but not by much (considering two of the canakit stereos is $32, then also the speakers, and the wires, and the time, etc, sounds like a good deal to me).
- iComm (Imperial Communication System): http://www.whitearmor.net/forum/topic/14832-fs-imperial-communication-system-icomm/and their website http://store.voicebooster.com/icomm-imperial-communication-system/ is a one stop shop for a wireless mic, an Aker amplifier, and the iComm static burst voice card. $105.50 for the iComm, $48 for the Aker amp, and $30 for the wireless mic.
- Echo's Helmet Fan System: http://www.whitearmor.net/forum/topic/24372-fs-helmet-fan-system-echos/A really nice fan system, puts 2 in your bucket up near the cheeks on independent power systems. They're $70 for the whole kit (add $15 for custom name!)
With the above bundles, I should be able to customize my helmet about the same level. Pricier to be sure than just buying the components separately (about $300), but a lot of saved time and headache for people like me
The only thing I'm missing now is an intercom to chat w/other troopers...

Edit: As an alternative to the iComm hooked up to a wireless mic and amp in the breastplate, ukwrath has these speakers embedded in the Hovi's of the helmet (the nubs at the jaw level). He sells them at http://www.whitearmor.net/forum/topic/31436-fs-ukswraths-hovi-mic-tips-with-speakers-crl-accurate-tips/ between $60 and $140. The lower end is just the speakers, up to you to get everything else. The upper end includes an amp and even an iComm (so complete Stormtrooper chatter). These speakers won't be as loud as the ones with the iComm, but "good enough" for most trooping needs. Plus, has the advantage of *everything* in the bucket (and won't need a wireless mic).
