The vendors are good and reliable to order from, esp Marcus from what I hear. As for the parts you can order just the parts you want, you don't need to order the whole kit. As for parting out just look in the classifieds section as every now and then ppl put up their kits for sale and are sometimes will to part out. Depends what kit you're specifically referring to as well. OEM USDM kit is a lot easier to get than a Mugen or Euro-R kit for instance no waiting period and the price will be a lot lower. Mugen is out of your price range from what you listed but just as an example I put it in there. Pending on the choice you go with though you may want to get side skirts because the lip kit is lower than the stock kit so you will see the front and rear sitting lower than the sides and will kinda look outta place, like __O----O__, obviously not THAT low but that is kinda the idea.
