I'm interested in upgrading and getting a SRAM Red groupset. I haven't decided if I should find deals on separate components (e.g. ebay, etc.) or be patient until I find a dealer/seller with a good price on the group.

Just curious what you guys have done. Any advice is much appreciated.

Some people are going to tell you they purchased individual components and some people are going to tell you they purchased groups. Both ways work.
Make a list of the components you want, check ebay completed auctions (or other sites) and write down the average each component sold for (which will be representative of what you will pay) then compare against what complete groups are selling for.
