bought together or a piece at a time, the price is pretty consistent. Frames (no grips/stocks if you plan on going custom there also) are $200-230, with wood or composite $280-310, then add the barrel you want ($220-???). But all the custom gun guys have pricelists on their sites. Some include extras, like VVCG price on Encore frames includes a trigger job (which IS cheaper than buying a frame and then having a trigger job, if nothing else you save the extra shipping back and forth).
