Hi folks- After doing a lot of lurking here and other ceramic forums, I took the plunge and bought 2 Lg BGE. Now the fun begins! Had a few questions though:1. Accessories- I read good things about the adjustable rig/spider combo available on eggaccessories.com. If I got this, would there be any reason to get the plate setter? How about the 3-tier grill extender?2. Searing- Did I read somewhere that I could put a Med size grid closer to the firebox for searing? Is this the same size I would need if I utilized the spider instead?Thanks in advance! I'm sure I'll have more questions..."Randawg" Randy
