I've been using LancerShop for all my modifying needs since purchasing my Evolution VIII upon my return from Afghanistan last year. Absolutely amazing communication and they are very quick to get the parts to your door. Each order is documented/archived along with every tracking number, which is great for maintenance records and customer reassurance. They've taken great care of me and I highly recommend. I don't trust anyone else online more than LancerShop.
