I thought about buying from Trooperbay, but was turned off by his price. It's way too expensive. If you guys want to know where I got mine, I got it on eBay from a seller called "sitharmor" for about $15. I didn't consider being a TX back then, so I got the one with orange coloring. I recently sprayed the orange parts black. It works for me.
However, they're only $15 for a reason; there's better options out there. Like I said before, trooper1 on MEPD is your best bet at finding a decent pauldron, no matter what color you're looking for. You'll have to contact him yourself to get information on pricing, shipping, etc
