PG, Classic Industries, Year One, etc sell the same stuff depending on what you're looking for. Best bet is to build a wish list with each company and wait for the 30% sale dates as posted under the Hot Deals forum.
I do appreciate that PG sells parts (dash bezel specifically) individually. But sometimes they are higher from the get go. It's an open market and alot of what you may need is also available on eBay, same stuff as what the big name sellers have, with no shipping hassles. Do your homework on what you want and carefully pull the trigger. If you can make it, hit the major shows- Carlisle can be an awesome weekend-
